ulab.utils

ulab.utils.spectrogram(r: ulab.numpy.ndarray) → ulab.numpy.ndarray

Parameters:

r (ulab.numpy.ndarray) – A 1-dimension array of values whose size is a power of 2

Computes the spectrum of the input signal. This is the absolute value of the (complex-valued) fft of the signal. This function is similar to scipy’s scipy.signal.welch https://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.welch.html.
