In this question, we use MATLAB to implement a sampling and reconstruction of the signal Jent-2nt, 0≤t≤2 0, otherwise f(t)= = (a) Use MATLAB to plot the signal for 0 ≤t≤ 2. (b) Use MATLAB to plot the amplitude spectrum f(a) for -12 ≤ a ≤ 12. In the following questions, we assume that f(t) is bandlimited to 12Hz. (c) Pick a suitable sampling rate such that f(t) can be reconstructed from the samples. Plot the sampled signal.

(a) Use MATLAB to plot the signal for 0 ≤ t ≤ 2
(b) Use MATLAB to plot the amplitude spectrum f(a) for -12 ≤ a ≤ 12. In the following questions,
we assume that f(t) is bandlimited to 12Hz.
(c) Pick a suitable sampling rate such that f(t) can be reconstructed from the samples. Plot the
sampled signal.
(d) Choose a suitable value Mo as a threshold for low-pass filter. Use MATLAB to reconstruct the
original signal using Shanon's sampling formula.
(e) Plot the reconstructed signal by itself, and then plot it superimposed over the original signal f.
