dsp principle and application are as follows:
DSP principle is the use of computers or special processing equipment, in digital form of the signal acquisition, transformation, filtering, valuation, enhancement, compression, identification and other processing, in order to get the form of the signal that meets the needs of people.
The main applications of DSP chips are:
1, signal processing - such as, digital filtering, adaptive filtering, Fast Fourier Transform, correlation operations, spectrum analysis, convolution and so on.
2, communication - such as, modem, adaptive equalization, data encryption, data compression, back slope offset, multiplexing, fax, spread spectrum communication, error correction coding, waveform generation.
3, Speech - e.g., speech coding, speech synthesis, speech recognition, speech enhancement, speaker identification, speaker confirmation, voice, speech storage, etc.
4, Image/Graphics - such as 2D and 3D graphics processing, image compression and transmission, image enhancement, animation, robot vision, etc.
5, Military - such as confidential communications, radar processing, sonar processing, navigation, etc.
6, instrumentation - such as spectrum analysis, function generation, phase-locked loop, seismic processing.
7, automatic control - such as engine control, deep space, automatic driving, robot control, disk control.
8, medical - such as hearing aids, ultrasound equipment, diagnostic tools, patient monitoring.
