Question:
(a) Show that the kernels K(τ) in Eq. (6.47) produce the indicated outputs w(t). Deduce the ratio Sw(f)/Sy(f ) =|K̃(f)|2 in two ways:
(i) By Fourier transforming each K(τ);
(ii) By setting y = ei2πft , deducing the corresponding filtered output w directly from the expression for w in terms of y, and then squaring to get|K̃ (f)|2.
(b) Derive Eqs. (6.52b) and (6.52c) for the kernel (6.52a).
Data from Eq. (6.47)
