As you probably know, analog and digital circuit are the foundation of the electronics industry. What’s more, analog circuit mainly refers to amplifier, oscillating circuit, feedback, various operational circuits and so on; While the digital circuit includes combinatorial logic and sequential logic.

Apart from that, the so called analog signal means that analog electronic signal is continuously changing in both time and value.

The digital electron adopts binary, which has plenty of pros such as strong anti-jamming ability, high precision, long storage time, terrific confidentiality and high generality, etc.
