What is a Coupling Capacitor : Construction & Its Working
Coupling Capacitor Construction. Coupling capacitors are mainly used in analog circuits whereas the decoupling capacitors are used in digital circuits. The connection of this capacitor can be done in series with the load for AC coupling. A capacitor blocks low-frequency signals like DC and allows high-frequency signals like AC.
