While amplifiers have to have a DC operating power for its internal bias set up. This same bias voltage could be betransferred to the output as unwanted bias voltage, T his voltage can upset the next amplifier bias voltage and so on. a capacitor will block this DC bias voltage and a resistor can be used to restore next amplifier bias point.
