javascript - how to display result in other text box with condition in jquery -

-

i have field enter image description here

as shown in figure, if enter less 20 in result field nor/ab value should automaticaly changes "low" if entered more 110, should display high else normal. tried jquery , did not successed...let see form.

<div style=" width:900px; height:auto; float:left; text-align:center;"> <div style=" height:auto; width:140px; float:left">{title}</div> <div style=" height:30px; width:140px; float:left"><input type="text" height="30px" width="140" name="rep_result_{txt}"  /></div> <div style=" height:30px; width:140px; float:left">{unit}</div> <div style=" height:30px; width:140px; float:left">{first_val}&nbsp;-&nbsp;{last_val}</div> <div style=" height:30px; width:140px; float:left"><input type="text" height="30px" width="140" name="remark_{txt}" >

you can see entered range value in 2 section first_val(means 20) , last_val(means 110), how can use jquery make complete(remember range value dynamic can't apply condition on 20,110)...thanks in advance

html

<input type='text' id='result' /> <input type='text' id='nor' data-min='20' data-max='110' />

javascript

$('#result').change(function() {     var result = $(this).val(),         nor = $('#nor'),         min = nor.data('min'),         max = nor.data('max');     if(result < min) {         nor.val('low');     } else if (result < max) {         nor.val('normal');     } else {         nor.val('high');     } });

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...
