Each stage of a three stage RC coupled amplifier has a voltage gain of 10. How much is the overall voltage gain? What is the voltage gain in dBs

The overall voltage gain = 60dB

Step-by-step explanation:

Voltage gain in decibel can be expressed using the equation,

Av in dB = 20 log ( Vout / Vin)

Given that each stage of a three stage RC coupled amplifier has a voltage gain of 10. 

First stage : 20log 10 = 20

Second stage = 20

Likewise the third = 20

The overall voltage gain = 60 dB
