:mod:`ulab.scipy.signal`
========================

.. py:module:: ulab.scipy.signal





.. py:function:: spectrogram(r: ulab.numpy.ndarray) -> ulab.numpy.ndarray

   :param ulab.numpy.ndarray r: 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``.
