Solution 1

To find X(k) for k = 5, 6, and 7, we need to refer to the given Fourier equivalent X(k) = {36, 4 - j9.656, -4 + j4, 4 - j1.6569, -4}.

Step 1: Determine the values of X(k) for k = 5, 6, and 7.

For k = 5, X(5) = ?

For k = 6, X(6) = ?

For k = 7, X(7) = ?

Step 2: Substitute the values of k into the given Fourier equivalent X(k).

For k = 5, X(5) = 4 - j1.6569

For k = 6, X(6) = -4

For k = 7, X(7) = Not given in the given Fourier equivalent.
