+(Power Spectral Density) for a given time-series signal. The
+functionality is provided by a method of the <tt>ao</tt> class called

+which implements the Welch method of averaging modified periodograms (also referred to
+as WOSA). More details can found in the dedicated <a href="sigproc_psd.html" >section</a> of the user manual.

+<p>In this tutorial, we propose the following exercises based on the
+estimation of the PSD of suitable time-series data:</p>
