How do ceramic capacitors work on the circuit?

Main tasks of ceramic capacitors on the circuit are coupling, decoupling, smoothing and filtering.

(1) Coupling
In this process, ceramic capacitors remove DC components and pass only AC components.

(2) Decoupling
In this process, ceramic capacitors remove unnecessary noise components.

(3) Smoothing
In this process, ceramic capacitors smooth voltage after rectifying and make voltage nearer to DC.

(4) Filtering
In this process, ceramic capacitors corporated with coils and resistors remove signals in unnecessary frequency bands and pass only signals in necessary frequency bands.
