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.
