Solution 1

To find the DFT of x*(n), we can follow these steps:

  1. Take the complex conjugate of each element in the sequence x(n) to obtain x*(n).
  2. Calculate the N-point DFT of x*(n) using the same formula as for x(n).
  3. The result of this calculation will be the DFT of x*(n), denoted as X*(k).
