1)The Open Loop Transfer Function of a unity feedback system is G(s)=k/〖(s+a)〗^n .Determine the Gain K for Closed loop response to be oscillatory and also determine the oscillating frequency?
2)For the above Open loop transfer function
(a)Determine Phase Crossover Frequency and G.M?
(b)Determine Gain Crossover Frequency and P.M?
3)Give the CONCLUSIONS after answering the TWO Questions?

min. k required is required to cause oscillation is 2*a^n (n+1/n-2)
min. k is 2*a^n(n+1/n-2) for oscillations
min. k is 2*a^n(n+1/n-2)
