1. A length-10 discrete-time signal x[n] is defined by the
values { 6, 1, 1, 6, 1, 1, 6, 1, 1, 0 }.

After taking the 10-pt DFT, X[k], determine the DC value, i.e.,
X[0].

2. Suppose that the N-point DFT of the signal x[n]x[n] is X[k]. A new signal y[n] is formed by adding a constant:

y[n]=x[n]+1 for n=0,1,2,…,N−1n=0,1,2,…,N−1

The N-point DFT of Y[k] is:
