Consider the sequence x[n] given by x[n] = ?n u[n]. A periodic sequence x[n] is constructed from x[n] in the following way:

[n] = x[n +r N]. x[n +rN].

(a) Determine the Fourier transform X(ej?) of x[n].

(b) Determine the discrete Fourier series X[k] of x[n].

(c) How is X[k] related to X(ej?)?

[n] = x[n +r N]. x[n +rN].
