Topic: Signals and Systems
The Fourier Transform of a discrete and aperiodic signal is
- A. Continuous and aperiodic
- B. Continuous and periodic
- C. Discrete and aperiodic
- D. Discrete and periodic
Answer: B. Continuous and periodic
Explanation: The discrete nature of a signal in one domain leads to a periodic nature in the other domain. The aperiodic nature in one domain leads to a continuous nature in the other domain. Therefore, the Fourier transform (DTFT) of a discrete and aperiodic signal is continuous and periodic.
