Given the sinusoid x(n)=2sin(200pi.n/8000) obtained by samplingthe analog singnal x(t)=2sin(200pi*t), with samplinf rate of fs=8000Hz.
A) Use the matlab DFT to compute the signal spectrum with the frequency resolution to be equal to or less than 8Hz.
B) Use the matlab FFT and zero padding to compute the signal spectrum , assuming that the data samples are available in(A).
