Expert Solution
Step 1

Given: 

Brief description:

In the above given question we have a common emitter amplifier circuit.

 

For the given above amplifier circuit we need to calculate  value of voltage gain.

 

Whenever we have bypass capacitor is connected in the emitter terminal the gain of the circuit will reduce.

 

This emitter resistance will work as a negative feedback element.

 

In the calculation of  voltage gain here we have used T model.

 

Av = ?.
