The chapter delves into the frequency response of Common Emitter (CE) and Common Source (CS) amplifiers, focusing on their behavior under varying conditions including self-biasing. It emphasizes critical frequency-dependent components that affect gain, ultimately providing a condensed analysis through numerical examples. Practical guidelines and comparisons are established for designing amplifiers suitable for audio applications.

Term: Common Emitter Amplifier
Definition: A type of amplifier configuration that provides significant voltage gain and is characterized by its frequency response influenced by reactive components.
Term: Frequency Response
Definition: An analysis that describes how the output of an amplifier responds to different frequencies of input signals, determined by poles, zeros, and corner frequencies.
Term: Poles and Zeros
Definition: Poles are frequencies at which the gain of the amplifier drops significantly, while zeros are frequencies at which the gain increases; both define the amplifier's frequency response.
Term: Cutoff Frequency
Definition: The frequency at which the output signal of an amplifier falls to a certain threshold, defining the effective bandwidth of the amplifier.
