1(a) The function X(t) is defined as follows

X(t) =∑_(n= -∞)^∞▒〖δ(t-nT)〗

Draw this periodic function, then determine the fourier series coefficients αk, and the fourier transform X(w)

b) given X(t)=sin〖(2πt)〗,

i) determine X[nT1) for -6 ≤ n ≤ 8 and T1 corresponding to a sampling rate of 4Hz

i) determine X[nT2] for -6 ≤ n ≤ 8 and T2 corresponding to a sampling rate of 2Hz

c) Explain the difference between normal sampling, oversampling and under sampling.
