![]() ![]() However, for one-sided transforms, which are the default for real signals, spectrogram uses 1024 / 2 + 1 = 513 points. You can specify this number if you want to compute the transform over a two-sided or centered frequency range. Pspectrum always uses N DFT = 1024 points when computing the discrete Fourier transform. The leakage ℓ and the shape factor β of the window are related by β = 40 × ( 1 - ℓ ). Pspectrum always uses a Kaiser window as g ( n ). Specify the window length and overlap directly in samples.
