What are the characteristics, advantages and disadvantages of analog circuits and digital processing?

1. In a cycle, the current and voltage of analog circuits are constantly changing, while in digital circuits, their current and voltage are fluctuating.

2. Analog circuits and digital circuits are also carriers of signal changes. Analog circuits amplify and reduce signals through the amplification characteristics of components (such as transistors), while digital circuits transmit signals through switching characteristics (such as transistors).

3. In the analog circuit,

The changes of voltage, current, frequency and period are mutually restricted, while the changes of voltage, current, frequency and period in digital circuits are discrete.

4. Analog circuits can work under high current and high voltage, while digital circuits can only complete or generate stable control signals under low voltage and low current consumption.

5. The analog circuit supplies power for the digital circuit to complete the execution of the actuator. Digital circuit completes the operation process of the whole circuit through its unique logic operation.

6. Because the digital circuit deals with logic level signals, from the point of signal processing, the digital circuit system has higher signal anti-interference ability than the analog circuit.
