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

52 <p>
53 Given an input analysis object (can be a time series or a frequency series object)
54 <tt>a_in</tt>, digital filtering operation can be easily performed:
55 </p>
56
57 <div class="fragment"><pre>
58
59 a_out = filter(a_in,fobj)
60
61 </pre></div>
62
63 <p>
64 Where <tt>fobj</tt> is a filter. It can be a <a href="sigproc_iir.html">MIIR</a>,
65 a <a href="sigproc_fir.html">MFIR</a>
66 or a <a href="sigproc_filterbanks.html">FILTERBANK</a> object.
67 </p>
68 <p>
69 The filter object <tt>fobj</tt> can be also embedded in a plist
70 </p>
71
72 <div class="fragment"><pre>
73
74 pl = plist(<span class="string">'filter'</span>, fobj);
75 a_out = filter(a_in,pl)
76
77 </pre></div>
