An amplifier circuit can be designed using transistors or operational amplifiers. A transistor can operate in three states – Cutoff state, Active state, and Saturation state. In active state, the transistor acts as an amplifier so by configuring transistors in active state, they can be used to construct audio amplifiers.

Amplifier Circuits Introduction to Impedance and Bandwidth Control. Modified Response Curves Previous modules have concentrated on producing a flat frequency response over the required audio frequency range. It is sometimes necessary however, to modify the flat response of an audio amplifier by making particular stages of the amplifier frequency

It is pretty much just a bit less than R4, say 40k, but it needs to have a capacitive reactance equal to R4 at the lowest frequency we intend to amplify. If we choose 40Hz Xc = 1/ (2πfC), then C = 1/2πfXc = 0.39uF. In the same way, C2 = …
