Construction of a Two stage RC Coupled Amplifier

RC Coupled Amplifier FAQs

The commonly used coupling methods are R.C. coupled Transformer-coupled Direct-coupled

The bypass capacitor at the emitter offers a low reactance path to the signal. As it allows more flow of the signal than the normal circuit path.

The ratio of output voltage to the input voltage is known as the amplification or voltage gain of the amplifier. Also called the loop gain, denoted as

Cascading means the output of the first stage is connected to the input of the second stage through a suitable coupling device and so on. The coupling devices are generally capacitors, transformers, etc.

The bandwidth of an RC coupled amplifier lies between 50 Hz to 20kHz.
