Question: Consider an LTI system with |H(e j? )| = 1, and let arg[H(e j? )] be as shown in Figure. If the input is x[n]

Consider an LTI system with |H(ej?)| = 1, and let arg[H(ej?)] be as shown in Figure. If the input is

x[n] = cos (3?/2 n + ?/4),

determine the output y[n].

arg[H(e ] 5T/6 m/2 Slope = - 1/3 Slope - 1/3 -

arg[H(e ] 5T/6 m/2 Slope = - 1/3 Slope - 1/3 - n/2 -5n/6
