The chapter explores the frequency response of CE and CS amplifiers, particularly focusing on R-C circuits. It examines the transfer function, gain plots, and phase plots to illustrate how these circuits behave across different frequency ranges. Additionally, it highlights the significance of poles in determining the cutoff frequency and overall performance of amplifier circuits.

Term: Transfer Function
Definition: A mathematical representation that defines the output response of a system for a given input, evaluated in the Laplace domain.
Term: Cutoff Frequency
Definition: The frequency at which the output power of a circuit drops to half its maximum value, commonly characterized in the context of amplifier frequency response.
Term: Bode Plot
Definition: A graphical representation of a system's frequency response, displaying magnitude and phase across frequencies on a logarithmic scale.
Term: Poles and Zeros
Definition: Poles are values of s in the Laplace domain that cause the output to become infinite, while zeros are values that cause the output to become zero, impacting the system's frequency response.
