+ − <h2><a name="Applyfiltdesc">Description</a></h2>
+ − <p>
+ − Digital filtering in LTPDA can be performed by a call to the <tt>ao/filter</tt> method.
+ − <tt>ao/filter</tt> method is a wrapper of the standard MATLAB filter method.
+ − Details of the core algorithm can be found in the proper
+ − <a href="matlab:doc('filter')">documentation page</a>.

+ − <h2><a name="Applyfiltexample">Examples</a></h2>
+ − <p>
+ − Given an input analysis object (can be a time series or a frequency series object)
+ − <tt>a_in</tt>, digital filtering operation can be easily performed:
+ − </p>
+ −
+ − <div class="fragment"><pre>
+ −
+ − a_out = filter(a_in,fobj)
+ −
+ − </pre></div>
+ −
+ − <p>
+ − Where <tt>fobj</tt> is a filter. It can be a <a href="sigproc_iir.html">MIIR</a>,
+ − a <a href="sigproc_fir.html">MFIR</a>
+ − or a <a href="sigproc_filterbanks.html">FILTERBANK</a> object.
+ − </p>
+ − <p>
+ − The filter object <tt>fobj</tt> can be also embedded in a plist
+ − </p>

+ − <div class="fragment"><pre>
+ −
+ − pl = plist(<span class="string">'filter'</span>, fobj);
