thanx

page : like.php

<span id="like1" onclick="ajaxfun(1)">like</span><br /> <span id="like2" onclick="ajaxfun(2)">like</span><br /> <span id="like3" onclick="ajaxfun(3)">like</span><br /> <span id="like4" onclick="ajaxfun(4)">like</span><br /> <span id="like5" onclick="ajaxfun(5)">like</span><br /> .... <span id="like10" onclick="ajaxfun(10)">like</span><br />

page : ajaxx.js

function ajaxfun(id) {     document.getelementbyid("like"+id).innerhtml="wait !!!";     if (window.xmlhttprequest) {         // code ie7+, firefox, chrome, opera, safari         xmlhttp=new xmlhttprequest();     }     else {         // code ie6, ie5         xmlhttp=new activexobject("microsoft.xmlhttp");     }     xmlhttp.onreadystatechange=function() {         if (xmlhttp.readystate==4 && xmlhttp.status==200) {             var getdata=xmlhttp.responsetext;             if(getdata=="ok") {                 document.getelementbyid("like"+id).innerhtml="unlike";             }             else {                     document.getelementbyid("like"+id).innerhtml="like";             }         }     }     xmlhttp.open("get","verify.php?id="+id,true);     xmlhttp.send(); }

page : verify.php

it verify , if done returns ok else not ok

error :(

like like wait !!! wait !!! wait !!! wait !!! wait !!! wait !!! unlike

just set array ajax handlers...

var arrajaxhandlers = []; function ajaxfun(id) { document.getelementbyid("like"+id).innerhtml="wait !!!"; if ( arrajaxhandlers[ "like"+id ] == null ) {     if (window.xmlhttprequest) {         // code ie7+, firefox, chrome, opera, safari         arrajaxhandlers[ "like"+id ]=new xmlhttprequest();     }      else {         // code ie6, ie5         arrajaxhandlers[ "like"+id ]=new activexobject("microsoft.xmlhttp");     } } arrajaxhandlers[ "like"+id ].onreadystatechange=function() {     if (arrajaxhandlers[ "like"+id ].readystate==4 && arrajaxhandlers[ "like"+id ].status==200) {         var getdata=arrajaxhandlers[ "like"+id ].responsetext;         if(getdata=="ok") {             document.getelementbyid("like"+id).innerhtml="unlike";         }         else {                 document.getelementbyid("like"+id).innerhtml="like";         }     } } arrajaxhandlers[ "like"+id ].open("get","verify.php?id="+id,true); arrajaxhandlers[ "like"+id ].send(); }

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
