ulab.scipy.signal

ulab.scipy.signal.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.spectrogram.
