96. Effect of feedback on frequency response (Part-B)
The chapter discusses the impact of feedback on the frequency response of electronic circuits, focusing on the behavior and location of poles in feedback systems. It explores the conditions under which poles can become dominant, complex, or conjugate pairs, influenced by various parameters in the circuit. The analysis encompasses multiple cases where different configurations of forward amplifier and feedback network affect the system's stability and response characteristics.

The location of feedback system poles can be significantly altered by feedback, affecting overall circuit behavior.
Both real and complex conjugate poles can arise depending on the configuration of the amplifier and feedback network.
Understanding the dominant pole and its shift is crucial for predicting system stability and frequency response.
Dominant Pole
The pole in a system that has the most substantial influence on the system's behavior, particularly near the origin on the s-plane.
Complex Conjugate Poles
Pairs of poles that are complex numbers and occur due to the interaction of real poles, significantly affecting the transient response of the system.
Bode Plot
A graphical representation of a system's frequency response, displaying the gain and phase shift across a range of frequencies.
