Paper Details

In Section 2.9.6, it was argued intuitively that
Y(ej?) = H(ej?) X(ej?),
When Y(ej?), H(ej?), and X(ej?) are, respectively, the Fourier transforms of the output y [n], impulse response h[n], and input x[n] of a linear time-invariant system; i.e., Verify Eq. (p2.75-1) by applying the Fourier transform to the convolution sum given in Eq. (p2.75-2).
