Question
If X(k) is the N-point DFT of a sequence x(n), then what is the DFT of x*(n)?Select one:a. None of the mentionedb. X(N-k)c. X*(N-k)d. X*(k)
Solution
To find the DFT of x*(n), we can use the property that the DFT of the complex conjugate of a sequence is equal to the complex conjugate of the DFT of the original sequence.
Given that X(k) is the N-point DFT of x(n), the DFT of x*(n) can be represented as X*(k), where X*(k) denotes the complex conjugate of X(k).
Therefore, the correct answer is option d. X*(k).
