Digital Signal Processing Experiment Based on Matlab: Parseval’s Theorem, Time Domain Energy = Frequency Domain Energy, Unitary Matrix
The last experiment in class on October 13 was to prove this. I wasn’t very good at manual proofs, but a numerical simulation code solved it in no time. It has been inconvenient to write mathematical formulas on WeChat, so I delayed for more than a month before writing this article.The Fourier transform is often … Read more
