Coupling and Decoupling | Applications | Capacitor Guide
Coupling capacitors. While decoupling capacitors are connected in parallel to the signal path and are used to filter out the AC component, coupling capacitors, on the other hand, are connected in series to the signal path and are used to filter out the DC component of a signal. They are used in both analog and digital circuit applications.
