A Query about "Improvements to the Sliding DFT Algorithm"
Started by 1 year ago●7 replies●latest reply 10 months ago●318 viewsHi all!
My first post here! Long time lurker first time poster.
This one is kinda specifically directed at @RickLyons but happy for anyone to answer.
I am reading: https://www.researchgate.net/publication/352874961......
When performing an FFT, modifying the magnitude spectrum in some arbitrary way, and then applying an inverse FFT, how should I handle circular convolution? How can...

IIR Filter Implementation in the Frequency Domain?
Started by 11 months ago●11 replies●latest reply 11 months ago●334 viewsSilly question: Is it possible to implement a IIR filter in the frequency domain just as you would a FIR filter? Or is the answer, "Well, you COULD, but that's a...
I'm looking again at an FSK demodulator.Currently using an arctan followed by a derivative which is giving good results. fred harris always recommends:f ~= (dI...
The error of manually computed inverse FFT increase along x-axis
