What is Decoupling Capacitor? Working and Uses

A decoupling capacitor is a capacitor used in electronic circuits to decouple one part of a circuit from another. It serves two primary functions: Filtering out Noise: It filters out high-frequency noise or transients on the power supply lines. Stabilizing Voltage: It provides a local reservoir of charge to stabilize the voltage supplied to an […]
