“Welcome to Perfect Knowledge!
Today we’ll learn how a basic electronic amplifier works.
An amplifier takes a small input signal and boosts it using an active device such as a transistor or an operational amplifier.
It uses resistors for biasing, capacitors for coupling, and a power source to provide energy.
The output is a stronger version of the same input signal, which can drive a speaker or another circuit stage.
Let’s look at the circuit diagram and understand it step-by-step…”
