Signal Processing: Fourier Transforms and Wavelet Transforms

09 Nov 2020

This article does a good job of explaining what a fourier transform does!

fft applied on denoising time series:

paper on comparing effectiveness of wavelet transform (WT) vs fast fourier transforms (FFT) for denoising signal! - WT wins!

good stackoverflow post illustrating FFT for extrapolation (and its shortcomings!) -

now we get into WT; great article here:

potentially interesting paper combining wavelet and ARIMA approach…! to be read in more detail at a later time lolol:
