To perform filtering FFT on noisy data, you can use the following steps:
fft
functionfftshift
and ifftshift
functions to specify the frequency range to be filtered.*
operatorifft
function to obtain the filtered data in the time domainHere's the code implementation of the steps:
main.m578 chars28 lines
This will produce a plot of the original noisy data and the filtered data. You can adjust the filter parameters (cutoff frequency, filter type, etc.) as needed to achieve the desired noise removal effect.
