Input coupling capacitors are normally used with all types of bias circuits, otherwise the circuit bias conditions will be altered. A coupling capacitor is usually required at the output of a transistor circuit (as well as at the input) to couple to a load resistor, or to another amplification stage.
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.
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.
Coupling capacitors (or dc blocking capacitors) are use to decouple ac and dc signals so as not to disturb the quiescent point of the circuit when ac signals are injected at the input.
