WebIf you explain more about what you are trying to exttract from FFT it may help. Another technique you could try is Zero Padding. Fill a 8192 array with 1024 points of valid data , and fill rest with zeros. This will lead to interpolation of FFT output and give you 5hz resolution (in some sense) – Shutupandplay tuts. Web13 de mar. de 2015 · Normalization can be done in many different ways - depending on window, number of samples, etc. Common trick: take FFT of known signal and normalize by the value of the peak. Say in the above example your peak is 123 - if you want it to be 1, then divide it ( and all results obtained with this algorithm) by 123. Share.
