This article mainly discusses the difference between the communication circuit board and the decoding board.
Design principle
A communication circuit board is an electronic device used to transmit and receive signals, and its design principles mainly include signal modulation, demodulation, and signal amplification. The decoding board is an electronic device used to decode and restore signals. Its design principles mainly include signal decoding, signal processing and signal output.
The communication circuit board converts the information into a signal form suitable for transmission by modulating the original signal, then transmits the signal to the target device through the transmission medium, and finally restores the signal to the original information through demodulation. The decoding board is to restore the signal to the original information through decoding after receiving the encoded signal.
Working principle
The communication circuit board mainly transmits through analog signals or digital signals, which can realize long-distance transmission and high-speed transmission. The decoding board mainly transmits and processes digital signals, which can realize high-precision signal decoding and restoration.
Communication circuit boards need to consider signal transmission loss, noise interference and other issues during the transmission process, and a series of modulation and demodulation techniques need to be used to ensure reliable signal transmission. The decoding board needs to consider the decoding accuracy and restoration effect of the signal, and needs to adopt high-precision decoding algorithm and signal processing technology to realize it.
Application
Communication circuit boards are mainly used in communication equipment, radio equipment, network equipment and other fields to realize signal transmission and reception. The decoding board is mainly used in audio and video equipment, digital TV, digital broadcasting and other fields to realize signal decoding and restoration.
The communication circuit board plays a vital role in the field of modern communication. It is a key component to realize information transmission, which can realize information exchange between people and between people and machines. The decoding board is the key equipment to realize the decoding and restoration of audio and video signals, and can realize high-definition audio and video transmission and playback.
Performance requirements
Communication circuit boards need to have high transmission speed, low transmission loss and strong anti-interference ability. The decoding board needs to have high decoding accuracy, low signal distortion and good restoration effect.
The performance requirements of the communication circuit board mainly include transmission rate, transmission distance, signal quality and so on. The performance requirements of the decoding board mainly include decoding accuracy, signal distortion, restoration effect and so on.
