Filter capacitance:
It is connected between the positive and negative electrodes of the circuit, removing the useless AC current in the circuit, which generally adopts a large capacity electrolytic capacitor, and some other fixed capacitors.
Decoupling capacitance:
Connected to the positive and negative poles of the circuit, the parasitic oscillation caused by the positive feedback path formed by the internal resistance of the power supply can be prevented.
