Every practical system takes a finite time to reach its steady state and during this period, it oscillates or increases exponentially. The behavior of system gets decided by the type of closed loop poles and locations of closed-loop poles in s-plane. The closed loop poles are dependent on the parameters of the system. Every system … Continue reading Analysis of Second Order System
Negative feedback affects the performance of amplifiers to achieve the desired performance such as stability of gain, input/output resistance, Distortion less output, increnment in bandwidth etc.
It is a process of mixing a part of output signal with the applied input signal. Signal mixed with the applied input will be proportional to the output, it is called feedback signal. When source signal and feedback signal are in same phase then it is called positive feedback. An amplifier can behaves as a oscillator … Continue reading Basic Concept of Feedback
