If wp>ws, then the filter is a high pass filter. +If wp and ws are vectors of length 2, then the passband interval is defined by wp and the stopband interval is defined by ws. +If wp is contained within the lower and upper limits of ws, the filter is a band-pass filter. If ws is contained within the lower and upper limits of wp, the filter is a band-stop or band-reject filter.</p></div> + +<div class="refsection"><h3 class="title">Examples</h3> + <div class="programlisting"><table border="0" width="100%"><tr><td width="98%"><pre class="scilabcode"><span class="scilabopenclose">[</span><span class="scilabid">a</span><span class="scilabdefault">,</span><span class="scilabid">b</span><span class="scilabopenclose">]</span><span class="scilaboperator">=</span><span class="scilabid">ellipord</span><span class="scilabopenclose">(</span><span class="scilabnumber">0.2</span><span class="scilabdefault">,</span> <span class="scilabnumber">0.5</span><span class="scilabdefault">,</span> <span class="scilabnumber">0.7</span><span class="scilabdefault">,</span> <span class="scilabnumber">0.4</span><span class="scilabopenclose">)</span> +<span class="scilabid">a</span> <span class="scilaboperator">=</span> <span class="scilabnumber">1</span> +<span class="scilabid">b</span> <span class="scilaboperator">=</span> <span class="scilabnumber">0.20000</span></pre></td><td valign="top"><a href="scilab://scilab.execexample/"><img src="ScilabExecute.png" border="0"/></a></td><td valign="top"><a href="scilab://scilab.editexample/"><img src="ScilabEdit.png" border="0"/></a></td><td></td></tr></table></div></div> + <br /> + + <div class="manualnavbar"> + <table width="100%"> + <tr><td colspan="3" class="next"><a href="http://bugzilla.scilab.org/enter_bug.cgi?product=Scilab%20software&component=Documentation%20pages" class="ulink">Report an issue</a></td></tr> +<tr> + <td width="30%"> + <span class="previous"><a href="ellipap.html"><< ellipap</a></span> + + </td> + <td width="40%" class="center"> + <span class="top"><a href="section_cc2bc01c47967d47fcf3507a91d572ba.html">FOSSEE Signal Processing Toolbox</a></span> + + </td> + <td width="30%" class="next"> + <span class="next"><a href="enbw.html">enbw >></a></span> + + </td> + </tr></table> + <hr /> + </div> + </body> +</html> |
