How to learn digital and analog circuits?

Just please run a folk science and technology museum, to the majority of visitors nearly inexpensive to provide really effective substantive original design information. This is the true sense of patriotism, is the most efficient use of resources, is the greatest contribution to society, is to fundamentally improve the quality of the nation, enhance the international competitiveness of national industries. Charge goods in the market sales degree is large, large market share is based on trade secrets and other unspoken rules, even if the design and manufacture of advanced, is not necessarily justice. Your computers and cell phones are today's premium products. Do their manufacturers teach you to start from the basics and make innovative products that speak to them? They are now the whole set of design, procurement, production processes, testing technology, not to mention the core, key, even if the existing non-proprietary technology, are blocked droplets! Therefore, China is now said to "go to the market, the market to test". Are incompetent management level is a big manifestation. To start from the basic skills, production know-how published, must be combined with the daily necessities used by the general public to unveil the secrets of the industry; for the world's leading, the physical cost of its high price of high-grade luxury goods such as the next generation of keyboards, harmony telephone, playing electronic online games, high-speed response keyboard, etc., to the high reliability of the bicycle anti-theft locks, should be published in a variety of practical design, production of substantive information. By grasping the two ends, to guide, enlighten and inspire enterprises and individuals as well as students at school to design and manufacture their own mid-range, market-competitive wide range of products, is to improve the overall quality of the nation, which is what the ancients said; to take the law from the top, and only get to the middle; you see the high school scholar, post-doctoral, doctoral, and the effectiveness of the doctoral degree is even higher? Empty talk about innovation and transformation is a waste of social resources, waste of students' valuable youth time, ruin their future, and can not hold up their heads in front of developed countries and multinational companies. Doing hardware is very time-consuming, costly, without decades of continuous and uninterrupted experience, no financial support, no production practice verification, no business advice, it is empty talk, and can come out of the people are very rare, one is the elimination rate is high, one is the lack of money and time to support, and more importantly, many people, to the end of their lives, do not know where they are wrong? What didn't they do right? They simply do not know what the best approach is under the historical conditions and environmental constraints at that time. Or is it better to excel in science and take a high school entrance exam to be affordable and persuasive!!!! Employment is the overriding priority, fundamental to human survival!!!! Should the government give money to the poor? All the information on the design, processing, adjustment, and location of parts procurement of the exhibits in the Science and Technology Museum should be made public, so as to teach people to fish, and to improve the quality of the whole nation and the whole people. Nowadays, the teaching materials are all a big copy, now all the fashionable system integration, high-tech assemblers, with money to hit it. The strategic secrets of the country should of course be kept strictly confidential, and commercial secrets should be protected by the beneficiaries. Academic research done with social resources in foreign countries is usually completely open. In China, many researches done with state resources should be made public, and the teaching materials and experimental books of institutions of higher learning should be made public, or else academic corruption will be aggravated! This is a manifestation of responsibility for the use of state and social resources. In China, the public ownership of knowledge, the openness of the substance and the competition of technical means, the actual device can be reproduced free of charge in a third party, the technical indicators can be measured by an independent third party, the public performance comparison data, indicators, is the only way to completely enhance basic education across the long unattainable threshold, the state should pay the relevant costs; this is not a substitute for plagiarism. The next generation keyboard I designed 25 years ago has been disclosed internally at no cost in several industries because there are no patent applications to fund it and no labs. Provide innovative exhibits to science and technology museums and science exhibits, publicize all design, purchasing, processing, debugging, and maintenance information, and improve the basic quality of the nation. Who can tell me about the 70's and 80's ah To be close to life, talk about the experience of the older generation on the 70's teaching materials, industrial equipment, technological innovation information is completely open to the public, the whole country to learn from each other, unreservedly exchanged all over the world, raw materials, the highest utilization rate of equipment, from a variety of machine tools, automobiles, wire cutting machines, EDM machine tools, pumps, internal combustion engines, motors, clocks and watches, bicycles, lamps and so on. The spare parts are common and interchangeable throughout the country, the basic drawings are open to the public, the national unified design of the DDZ instrument, the national unified design of the N1 clock core, etc. In the 80's, the diploma, the education, the title says it all, and the whole thing is introduced. Consumption of social resources, damage to the interests of consumers, artificial trouble, creating maintenance difficulties, all the obstacles are to make more money, more money fraud. I to the national, provincial and municipal science and technology museums, are proposed to provide innovative exhibits, to be completely open to visitors all the design, processing, assembly, adjustment of information, the publication of raw materials, equipment, accessories purchasing location, allow the university is what the place? No matter how high the education and title, will not design and manufacture teaching aids, will not design and manufacture teaching instruments, will not maintain the instruments and equipment; with your parents' money to import teaching instruments to imitate the commissioned factory imitation is the best; with your parents' money to ask people outside of the school to repair equipment, procurement of spare parts from outside the school; with your parents' money to ask the production of teaching instruments to provide teaching experiments handouts, will be the author of the name of their on the There are awards for outstanding achievement in teaching; the formulas and foreign languages that you are taught to memorize can never compare to the contents of the textbooks that the Massachusetts Institute of Technology (MIT) of the United States has made public on the Internet. Students should not complain about the expensive tuition, in addition to the reasons of the teachers above, your own basic experiments, professional classes on the confused, high investment under the innovative experimental projects, Challenge Cup, science and technology competitions, graduation thesis, industry-university research, science and technology awards, business development, can not see the sunshine, will be the real money into a pile of garbage !!!! Nowadays, college students and graduate students themselves have no credit!!!! They are always thinking of doing "projects", which are at best downloading other people's designs, reading foreign language materials, organizing activities, creating an atmosphere, doing small business, etc., and spending money and cheating money on campus !!!!!!!!!!!!!! Allow visitors to download these materials, about no rebate to *****, so even if I am willing to give away, no one cares. sci for college students how to help? How can we utilize it? Thank you all report head:

should be capital letters SCI, EI. they can help you to graduate school, money, find a job, add honor, for the alma mater to compete, so that the school to you to increase investment. At the same time also corrupted the academic style, prompted plagiarism has long spread to the vast majority of undergraduate thesis, to the community and the country to create a huge potential social crisis, traitorous and unscrupulous professors, experts and social elites kidnapped the government, forcing the government to social individuals to inject huge amounts of money, raised tuition fees and national inputs, the large number of purchases of teaching and scientific research equipment caused by the equipment is idle, low rate of completion, high maintenance costs, equipment out of the very fast, Low utilization rate, high social cost of teaching costs, teachers cheated the high remuneration, a large number of imports of large-scale precision instruments and reagents, non-revenue consumption of a large number of social resources, and the formation of a more and more powerful vicious circle, in essence, is the hostile countries through the agents in China - traitors unlawful intellectuals to create a similar Star Wars on the society in the The essence is that hostile countries through their agents in China - traitors and illegal intellectuals to create a similar Star Wars on society in the corrosion and destruction of the aura of grandeur, is a superpower outside the theoretical virus spread, jeopardizing national security! More clever black trick is the agent of foreign hostile forces hypocritically induced us to put our national strength into the fight for the Nobel Prize in the air, to do those absurd subjects, but also to entice you just a little bit, and then imported the most advanced analytical instrumentation and equipment in foreign countries, to the developed countries of those top universities for training, enrollment, you will be able to achieve the highest realm of your dreams. This is a conspiracy created by traitors, delusional attempts to confuse and destroy the country's utopian fantasies; it is digging black holes and traps, and it is a compelling propaganda ploy to consume the national power in huge amounts and to kidnap the zhengfu through the universities to reward the intellectuals for publishing the papers of the three major searches. Nowadays, scientific and technological papers can represent the innovation level of the country, which is about to win the Nobel Prize. Intellectuals rely on foreign scientific and technological literature, imported equipment and reagents fabricated papers once published, you can raise the title, there are bonuses to hand, the beneficiaries are happy, they boasted that China's various theses have been mysterious, treacherous and unpredictable, God, God, heaven and earth, is outside the foreign hostile to China's external forces and their partners, bred by China's domestic speculators, advocates of domestic interests, social and economic interests of the country's science and technology, the elite teamed up to fabricate the national science and technology, and the publicity of the Chinese government. The elite teamed up to concoct the only direction of the country's scientific and technological development, demagoguery, luring the Chinese government to the path of bankruptcy, are all traps, tempting China to buy a large number of advanced instruments, study abroad and training, digging out, shortfalls in the national treasury, corruption credits, accelerated corruption of the black tricks.

This is the graduates find it difficult to find a job, enterprise products in the international competitiveness of the poor, can only do system integration, in the basic industrial capacity did not substantially improve, still lagging behind the developed countries for decades, and even 30 years ago, the basic level of China is not as good as, and the root cause of the social conflict is intense. Therefore, for China has a substantial significance of the real moves, practical work, is to use China's resources, from the foundation of manufacturing products with international competitiveness, and is a priority for national consumption. With huge social resources, imported equipment, imported integrated circuits to smash political achievements for the purpose of introducing talent, too dangerous!!!! To be strictly purged! No mercy! Three major search paper award shall not exceed one thousand dollars, can not be domestic production of materials, equipment into a leading commodity in the international arena, and rely on the procurement of foreign devices, reagents in the form of system integration to put together the paper, is the real money into garbage, is the trap of imperialism, the theory of the virus, greatly consume national resources, seriously promote corruption, blackmail the government, jeopardize the regime. Therefore, the way out of China's education is not a generalized openness, which is now too democratic and free, but to start from the foundation where problems abound, and solidity is the fundamental way. Mr. Zhang Ming said: various evaluation index systems, such as the number of papers in core journals, the number of international SCI and EI papers, the number of national subjects, the number of provincial and ministerial subjects, the total amount of funding for subjects, etc., are in fact only self-indulgence with Chinese academic characteristics. China's so-called academic core journals, its academic quality, originally known, but, in the case of various universities crazy pursuit of the number of papers, a university took the lead in the invention of the rigid provisions of postgraduate students to publish core journal papers as a prerequisite for graduation, artificially pulling up the number of thesis published by the school, and other schools have to follow suit, so that the essence of this illegal behavior, the new practice of colleges and universities. Graduate students can not do the paper, buy, not only buy the paper, but also buy space, various academic journals, thus selling space, a trend, further corrupting the quality of academic journals. The current situation is that, matching China's largest number of university students in the world, China also has the world's largest number of papers published, but the competitiveness of scientific research is declining year by year, the basic industrial capacity has not been substantially improved, and is still decades behind the developed countries. This is true for core journals and thesis publications, as well as for the so-called topics. Often, the bigger the official, the more topics, of course, the less time to do (this is assuming that they are all learned under the premise), can only let the students do, so graduate students have become the tutor's wage earners, cheap labor, such a topic, what quality, can be imagined. From the basic level of the teachers, the bottom line of morality, the ability to innovate, the sense of responsibility, the minimum sense of morality, from the Chinese bicycle and the developed countries of the bicycle of every detail of the comparison can be clearly differentiated, so that the substantive level of the subject and the dissertation you know it yourself. Teachers in schools, in the face of regular evaluations, must come up with something to make up the numbers, or they will be laid off. Of course, if the output is high, there are also rewards, especially in the so-called A grade B grade publications, the bonus is very substantial. Do anti-terrorism and anti-corruption need to be combined? So does counter-terrorism need to be combined with anti-corruption? Please tell us your views on the causes of the current world economic crisisSo we need to crack down on the four-in-one villains of political hooligans, academic hooligans, economic frauds and triad leadersWhat is bourgeois liberalization? That is, professors can not start from the ground up, relying on foreign imports of modules, reagents, integrated circuits, computers, instruments and equipment integration, but also to blackmail the government to bleed, to support the "high-tech" is to consume, waste of social resources. China's scarcity of what kind of equipment and technology sick intellectuals are not short of importing the most advanced international equipment, analytical instruments, such as Haas gear processing equipment, these top equipment, China has imported a lot of; not short of huge research funds. Just can not use this as the basis for manufacturing top mechanical equipment mother machine. The second prototype of the next-generation keyboard was handmade on the side of the road, and the Chinese mentioned as visitors to the exhibition illegal display to the Japanese at the booth, who immediately had to put it in their booth for the video camera; large Japanese companies used more than a dozen Chinese technicians to translate more than a hundred pages of the basic information and send it back to the mainland. And Overseas Chinese 8 Office forced the designers and manufacturers to retire early, the designers and manufacturers for more than 20 years have no instruments and equipment, working funds, no workplace; with high scientific research funds of high title, high education regardless of engineering technology, theoretical analysis, can not go beyond this step. What else do you think China lacks? Jiang Shuzhuo accused me of often improvising on the spot to answer students' questions in thesis and innovation projects, stealing the limelight, from design skills, processing industry, algorithms, patent document writing rules for everything, while his highly educated, highly titled characters are uneducated, stupefied, and pressurized to implement reverse elimination, forcing me to be laid off and unemployed in advance. This is the destruction of basic education, to combat innovation.
