In the application of modern science and technology, the same frequency phenomenon has been everywhere, involving communication, electronic equipment, medical equipment and other fields. In the field of communication, co-frequency communication refers to two or more devices transmitting information in the same frequency band. This communication mode has been widely used in radio communication, mobile communication, satellite communication and other fields.
The advantage of co-frequency communication is that it can save frequency resources and improve the efficiency of spectrum utilization, thus enhancing the stability and security of communication. However, different devices in the same frequency band will also bring different interference and influence. Noise interference is one of the most common co-frequency problems. Ordinary electrical equipment, electronic equipment, digital equipment, etc. It will produce a certain degree of noise interference, destroy the function and efficiency of surrounding equipment, and lead to the decline of communication quality.
Therefore, when designing a communication system, we must consider how to reduce the same-frequency interference and take appropriate technical measures to eliminate the interference.
A brief introduction to the background of the same frequency vibration phenomenon.
The same frequency vibration is a physical and technical term. It means that when a wave is emitted, it will produce a natural frequency, or a signal. When another wave vibrates at the same frequency or in the same vibration direction, it will have an enhanced effect and cause greater amplitude, which is called positive vibration. Or the vibration direction is opposite, resulting in the band weakening or even disappearing. This * * * vibration mode is reverse vibration.
We will receive a lot of information in our daily life. When this message can move people, it is called positive vibration. When people don't like or hate being far away, it means that the vibration direction is opposite, forming a reverse vibration.
