1. The principle of AD chip is to realize signal acquisition, processing and transmission by converting analog signals into digital signals. This is because the AD chip contains an analog signal sampling circuit, an analog signal conversion circuit and a digital signal processing circuit.
The analog signal sampling circuit samples the continuous analog signal at a certain time interval to obtain a series of discrete analog signal samples.
Analog signal conversion circuits convert these analog signal samples into corresponding digital signal samples, usually using an analog-to-digital converter.
The digital signal processing circuit processes these digital signal samples, such as filtering, amplification, coding, etc., to meet the specific application needs. 3. The principle of AD chip is widely used in many fields, such as audio processing, image processing, communication system and so on.
By converting the analog signal to the digital signal, the signal can be digitized, stored and transmitted, and the stability and reliability of the signal are improved.
In addition, the AD chip can also realize accurate sampling and processing of analog signals, improving the quality and accuracy of signals.
