a Consider the LTI system of impulse response - 2 - 2 n where a is some real parameter. What is the exact (necessary and sufficient) condition on a for the existence of a (nonzero) sinusoidal input of some frequency that is canceled by the system? Hint: Euler's formula. Q = 1 oasi O a = -1 GE[-1.1] E[-2.2] oa C[-2,0) All values of are possible. This is not possible for any value of a
