94. Feedback system (Part-E)

The chapter provides a comprehensive overview of feedback systems in analog electronic circuits, focusing on the voltage gain, input resistance, output resistance, and output voltage of feedback systems. It contrasts ideal and non-ideal feedback situations through numerical examples, illustrating how different parameters like gain and resistance interact in these contexts. Through various calculations, it emphasizes the impact of feedback on circuit performance, particularly in enhancing input resistance and modifying output resistance.
