BC:11.1A periodic sampled time function has the formula

a.) What is the period,N, for this signal?

b.)Use Matlab to display one complete cycle of f[n] in the range of 0?n?(N?1)

c.)Use Matlab to calculate the discrete Fourier transform,F[k], in the range of 0?k?(N?1) Plot the magnitude and phase (in degrees) of F[k] for this range of k.

d.) Use the data cursor tool the evaluate the magnitude and phase of F[0],F[8],F[32], andF[56]
