Step 1
Now, let's substitute the values into the formula: X[k] = Σ(x[n] * e^(-j*2πkn/2)) Since we only have one value for x[n], which is x[0] = 11, we can simplify the formula: X[k] = x[0] * e^(-j*2πk0/2) Now, let's calculate the exponential term: e^(-j*2πk0/2) = Show more…

If X(k) is the DFT of the sequence x(n), determine the N-point DFTs of the sequences x_c(n) = x(n) cos(2̀́k_0n/N), 0 <= n <= N-1 and x_s(n) = x(n) sin(2̀́k_0n/N), 0 <= n <= N-1 in terms of X(k).
