Problem on feedback system
What are the techniques used to make feedback system stable?
Explain and draw the frequency response of a 1-pole feedback amplifier.
In a 3-pole feedback amplifier the loop gain is given by:
t(f)=(Beta*100)/ ( (1+j*(f/10^4)) * (1+j*(f/10^5))^2 );
Determine the stability for Beta=.5 and .05. Sketch the Nyquist plot for both cases.
