A coupling capacitor is a capacitor which is used to couple or link together only the AC signal from one circuit element to another. The capacitor blocks the DC signal from entering the second element and, thus, only passes the AC signal.
Series Connection: Place the coupling capacitor in series with the signal path. The capacitor should be connected such that one end is connected to the output of the first stage and the other end to the input of the subsequent stage.
In order to place a capacitor in a circuit for AC coupling, the capacitor is connected in series with the load to be coupled. A capacitor is able to block low frequencies, such as DC, and pass high frequencies, such as AC, because it is a reactive device. It responds to different frequencies in different ways.
When the AC signals supply from the microphone to the o/p device, then the DC signal cannot pass because this signal gives the power to the parts in the circuit. On the o/p end, we get the AC signal. So a coupling capacitor is placed between two circuits so that AC signals supplies while the DC signal is blocked.
Whenever a capacitor is selected for coupling applications, there are some key parameters that need to consider like series resonant frequency, impedance, and equivalent series resistance. The value of the capacitance mainly depends on the frequency range of the application & the impedance of load or source.
It allows for low-frequency or high-frequency coupling. While coupling capacitors pass through AC signals to output, do pretty much the opposite; decoupling capacitors shunt AC signals to ground and passes through the DC signal in a circuit. Decoupling capacitors are designed to purify DC signals of AC noise.
