Consider a feedback amplifier for which the open-loop gain A(s) is given

Consider a feedback amplifier for which the open-loop gain A(s) is given by 1000 A(s) = (1 + 10)(1+ 105) If the feedback factor is independent of frequency, find the frequency at which the phase shift is 180, and find the critical value of at which oscillation will commence.
