35. Frequency Response of CE and CS Amplifiers (Part A)
The chapter delves into the frequency response of Common Emitter (CE) and Common Source (CS) amplifiers, specifically focusing on how the gain varies with frequency. It revisits the frequency response of RC and CR circuits to establish foundational concepts and connects them to the transfer functions crucial for analyzing amplifier behaviors. The significance of cut-off frequencies, pole-zero relationships, and Bode plots is also emphasized to help grasp amplifier design and analysis.

Frequency Response
Indicates how the output of a circuit responds to different input frequencies.
Transfer Function
