Why Coupling Capacitor Is Used
A coupling capacitor is used to block the flow of direct current while allowing alternating or signal currents to pass hence mainly used for joining two stages in radio and amplifier circuits. The decoupling capacitor works as the devices local energy storage. Why Is There Always A Coupling Capacitor Between A Signal Dr S S S Gandhy College Of Engineering And Technology Capacitive Coupling Wikipedia A coupling capacitor is used in this circuit in conjunction with a line trap. Why coupling capacitor is used . In such applications the signal is driven to the base of a transistor through a serially connected coupling capacitor. In signal transmission the coupling capacitor is part of a power line carrier circuit as shown in the schematic below. Understanding the different ways in which capacitors are used helps to enable the selection of the best sort of capaci...
