Explain the process in both the frequency domain and time domain (use diagrams and equations to make your explanation precise). (c) (20%) Find Q ( e j ) the DTFT of q [ n ] and sketch it. (d) (20%) Express Y ( e j ) in terms of X ( e j ) . Express Y ( e j ) in terms of X ( j ) . Sketch Y ( e j ) . (e) (20%) For W = 3 T s , how would you reconstruct x ( t ) from y [ n ] ? Explain the process in both the frequency domain and time domain (use diagrams and equations to make your precise).
