Analyze the circuit method（3）

Time constant analysis:

The time constant analysis method is mainly used to analyze the properties of the circuit composed of R，L，C and semiconductor diode. The time constant is a parameter reflecting the energy accumulation rate of the energy storage element, if the time constant is different. Although the circuit is similar in form and connection, it plays a different role in the circuit. The shared circuits include coupling circuit, differential circuit, integral circuit, clamping circuit and peak detection circuit.
