WebJun 11, 2024 · Hilbert transform can be used to estimate signal envelope The estimation is very accurate for tone signals. In general, it is accurate for narrowband carrier signals. The estimation performance degrades for wideband carriers, like sum of tones or white noise (broadband signal). WebApr 7, 2024 · Hi! Here's the code containing the simulated data for a single individual. Also, I think there might be a way to plot the outline of the frequency spectra without the envelope function because I saw some other student make a similar graph without it but I just can't figure out the code..
