a. Compute the 8-point FFT of the 8-point signal x = [6, 1, 0, 1, 6, 1, 0, 1].

b. Using the inverse DFT formula, express x as a linear combination of real-valued sinusoids.

c. Find two other signals, one of length-9 and one of length-10, that have the same 8-point DFT as x. These signals must not begin or end with zeros.

d. Compute the 4-point FFT of x by carrying out a single 4-point FFT.
