| Dec 5, 2014 at 6:55 | comment | added | sarthak | when you are talking of conditional stability you are assuming the oscillations will only occur when magintude of loop gain is unity. My question is why this? Why phase lag of 180deg not enough (sufficient condition) to cause oscillations in the negative feedback system by the reasoning that the fed back voltage will be in phase with the input and hence never dies? Shouldn't the magnitude of the oscillations rise and make the system unstable? | |
