Question:

Consider the sequence

\[x(n)=\delta(n)+2 \delta(n-1)-\delta(n-2)+\delta(n-3)\]

(a) Compute its length-4 DFT.

(b) Compute the finite-length sequence $y(n)$ of length- 6 whose DFT is equal to the imaginary part of the DFT of $x(n)$.

(c) Compute the finite-length sequence $w(n)$ of length-4 whose DFT is equal to the imaginary part of the DFT of $x(n)$.
