Question:
Suppose that y[n] is the output of linear time-invariant FIR system with input x[n]; i.e.,
(a) Obtain a relationship between the time-dependent Fourier transform Y[n, ?) of the output of the linear system and the time-dependent Fourier transform X[n, ?) of the input.
(b) Show that if the window is long compared to M, then?
Y[n, ?) ? H(ej?)X[n, ?),
Where H(ej?) is the frequency response of the linear system.
