For the LTI system in Figure,?
H(ej?) = e?j?/2. ? ? ? ? ? ? ?| ? | ????(half-sample delay).
(a) Determine a choice for T and hc(t) in the system of Figure so that the system in Figure with H(ej?) as specified is equivalent to the system in Figure.
(b) Determine and sketch y[n] when the input sequence is
x[n] = cos (5?/2 n ? ?/4),
as sketch in Figure.
