SOLVED: Problem IX [10 pts] The Fourier transform of a signal f(t) is shown below. Suppose that f(t) is sampled at a sampling frequency of 5Hz.1. Plot the spectrum of the sampled signal.2. Now suppose that an ideal anti-aliasing filter is applied to f(t) before sampling. Plot the magnitude and phase responses of this filter. Also, plot the spectrum of the sampled signal at the filter output. F(0)
