What is the correct normalization for a flat top window?
Hi, I have a question about FFT. Considering that I have a data vector of accelerations sampled with an accelerometer and that I want to apply a flat top window, in order to obtain the most accurate amplitude in the FFT, what would be the right code for normalization in this specific case?
I tried this one, but I’m not sure if it’s correct:
N=numel(data);
w=flattopwin(N);
X=2*fft(data.*w)/sum(w);
Thanks in advance for you help.Hi, I have a question about FFT.
