    Answer: 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
