Up: Assignment 9: Discrete Fourier
Previous: Play with the DFT
- Add a second frequency component to the signal, with
frequency 0.2. See what the DFT looks like.
- Try out a variety of values for the second frequency,
including 0.33, 0.49, 0.6, 0.8, and 0.9.
- Write a few paragraphs describing your experiments and what you
saw. Include interesting figures. Use the word ``aliasing''.
- For one or more of these signals, check Parseval's theorem.
