Coupling capacitors

Coupling capacitors are components used in electronic circuits to connect two stages of a circuit while allowing AC signals to pass through while blocking DC components. They play a crucial role in amplifier configurations by preventing DC biasing from one stage affecting another and ensuring that only the desired AC signals are transmitted. This allows for better signal integrity

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.
