Explain The Working Of Rc Coupled Amplifier With Circuit Diagram. An rc coupled amplifier is a part of a multistage amplifier wherein different stages of amplifiers are connected using a combination of a resistor and a capacitor. The below circuit diagram shows the working of the common emitter amplifier circuit and it consists of voltage divider biasing used to supply the base bias voltage as per the necessity.

Output of second stage. Working of rc coupled amplifier. Operation of rc coupled amplifier when an ac input signal is applied to the base of first transistor it gets amplified and appears at the collector load r l which is then passed through the coupling capacitor c c to the next stage.

Rc coupled amplifier circuit diagram.

Observe the output waveform on cro. The frequency response of the direct coupled amplifier is similar to low pass filter and hence it is also known as low pass amplifier. The configurations can be of the common emitter common collector or the common base. Now the amplified signal developed across r c is given to the base of the next transistor through a coupling capacitor c c.
