If X(k) is the N-point DFT of a sequence x(n), then what is the DFT of x*(n)?Select one:1. X(N-k)2. None of the mentioned3. X*(k)4. X*(N-k)
Question
Solution 1
To find the DFT of x*(n), we can follow these steps:
- Take the complex conjugate of each element in the sequence x(n) to obtain x*(n).
- Calculate the N-point DFT of x*(n) using the same formula as for x(n).
- The result of this calculation will be the DFT of x*(n), denoted as X*(k).
