AIM:
The aim of this experiment is to learn the concept of tuning a filter. The idea is to adjust the RC time constants of the filter so that in phase response of a low-pass filter, the output phase w.r.t. input is exactly 90 ᵒat the incoming frequency. This principle is utilized in distortion analyzers and spectrum analyzers, such self tuned filters are used to lock on to the fundamental frequency and harmonics of the input.
RESULTS:
1. We have designed the SELF TUNNED AMPLIFIER.
2. We have plotted the transient response.
