Frequency characteristic analysis: Frequency characteristic analysis is mainly used to analyze whether the frequency of the circuit itself is suitable for the frequency of the signal it processes. In the analysis, the center frequency, upper and lower limit frequency and frequency bandwidth shoul

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. Altho

AC equivalent circuit analysis：Ac equivalent circuit analysis is one way to separate the AC system from the circuit and analyze it separately. In AC equivalent analysis, the AC equivalent circuit diagram should be drawn first. The following principles should be followed in drawing the AC equivalent

DC equivalent circuit analysis:When analyzing the principle of the circuit, it is necessary to find out the DC path and the AC path in the circuit. DC path refers to the static bias of each semiconductor transistor and integrated circuit when there is no input signal.That is, their static operating
