Question
For a given 8-point discrete signal x(n), the Fourier equivalent is given as:
X(k) = { 36, 4 - j9.656, -4 + j4, 4 - j1.6569, -4 }
Find X(k) for k = 5, 6 and 7.
Solution
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.
