Electrical Engineering

given the sequences
x1 = cos (0.5*pi*n) + cos (0.25*pi*n) + cos (0.125*pi*n); for n = 0to 7;
x2 = sin (0.5*pi*n) - cos (o.25*pi*n) + sin (0.125*pi*n); for n = 0to 7;
plot the sequences and comment on the results. increasing thenumber of samples to n = 0 to 99, compute the DFT of the twosequences in MATLAB and plot the magnitude and phase of thecomputed DFTs. comment on the results
