Consider the signal x(t) with Fourier transform as shown 1) What is the minimum sampling rate for sampling this signal without causing aliasing? 2) Suppose the sampling rate is fs = 1.5 MHz . Plot the spectrum of the sampled signal. Give a precise plot. 3) Suppose the sampling rate is now fs = 4 MHz . Plot the spectrum of the sampled signal. Give a precise plot. Show how to recover the original continuous-time analog signal x(t). 4) Suppose we quantize the samples amplitudes (obtained with the sampling rate 4 MHz) to 128 levels. Find the resulting bit rate for the digital signal.
