Which of the following statements about the Discrete Fourier Transform (DFT) is true?

A) It can only be applied to continuous signals.

B) It provides a time-domain representation of the signal.

C) It converts a discrete-time signal into its frequency components.

D) It is not suitable for periodic signals.

Answer: C) It converts a discrete-time signal into its frequency components.

Explanation: The DFT is used to analyze discrete-time signals by transforming them from the time domain into the frequency domain, providing insights into their frequency content.
