Matched filter in the frequency domain
(1.5) (a) Consider the signal s(t) in 3(c). Assuming that the unit of time is a millisecond
and the desired frequency resolution is 1 Hz, use the function contFT to compute
and plot |S(f).
(b) Use the function contFT to compute and plot the magnitude of the Fourier trans-
form of the convolution s * SMF numerically computed in 3(d). Also plot for
comparison |S(f)12, using the output of 5(a). The two plots should match.
(c) Plot the phase of the Fourier transform of s✶ SMF obtained in 5(b). Comment on
whether the plot matches your expectations.
