php - How to append characters to the parent window's component -

-

i have link, when clicks, opens window of browser (specialchars.php)

function popup_specialchars()     {          var ht;         if(window.navigator.appversion.indexof("msie 5.01") == -1)             ht = 300;         else             ht = 720;         specialcharswindow = window.open         (             "/tradesciencejournalsystem/specialchars.php", "special_characters",             "resizable=yes,scrollbars=yes,height=" + ht + ",width=650,dependent=yes,alwaysraised=yes"         );         specialcharswindow.focus();     }  <a href="javascript:popup_specialchars();" class="special">insert special character</a> <textarea name="docarticletitle" cols="60" rows="14"></textarea>

specialchars.php

function insert_text(str)         {                     alert(str);              opener.append(str); // not working             this.window.focus();         }  <table border="1" id="table1" width="97%">                 <tr>                     <td align="center" class="specialcharlink"><a href="javascript:insert_text('&#x00e1;')"><span class="specialchar">&#x00e1;</span></a></td>                 </tr> </table>

now happens when link of special character clicks, insert_text() called.and alert shows special character.but want append character textarea of opener window.but not working.

how can denote textarea of opener window?

gave id textarea

<textarea name="docarticletitle" id="id1" cols="60" rows="14"></textarea>

and changed

function insert_text(str)         {                     window.opener.document.getelementbyid('id1').value += str;                     this.window.focus();         }

and start appending characters textarea.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
