I am having trouble understanding how the time width of the Kaiser window is determined from each parameter used in "pspectrum" for time-frequency analysis. Currently, I am using the code below:
pspectrum(W_mix,Fs,’spectrogram’,’FrequencyLimits’,[0 1.2e6],
‘FrequencyResolution’,9e4,’Overlap’,99,’Leakage’,0.75,’MinThreshold’,-95);
Here, w_mix is a waveform data of size 1×15000, and Fs is the sampling frequency, which is 1×10^8. I understand that the shape factor βbetaβ is 10 in this case, but how is the time width of the window function determined? According to the previous research I am referring to, the time width is supposed to be 20.52 μs, but I do not understand the calculation method. Could you please explain it to me?I am having trouble understanding how the time width of the Kaiser window is determined from each parameter used in "pspectrum" for time-frequency analysis.
