+<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>.
+</p>
+
+
+<!-- ===== Examples ===== -->
+
+<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);
+    a_out = filter(a_in,pl)
+    
+</pre></div>
