javascript - How to get the id of the textbox on keydown event of that textbox -

-

i have text box in page:

<td> <input type="text" id="approvers1" size="11" onkeydown="adduserskeydown(event)" style="width: 470px;" /> </td>

this js function:

function adduserskeydown(evtobj) {      if (evtobj.keycode == 75 && evtobj.ctrlkey) {          addusers(--input parameter--);     } }

now if press ctrl k in textbox must call javascript function named addusers(--input parameter--).. input parameter should id of textbox...

how achieve this.. either need id of textbox or atleast dom object can access id of textbox dom object..

kindly me in achieving either 1 of 2 things..

use this dom element or this.id id of element

<td> <input type="text" id="approvers1" size="11" onkeydown="adduserskeydown(event,this.id)" style="width: 470px;" /> </td>  function adduserskeydown(evtobj,id) {      if (evtobj.keycode == 75 && evtobj.ctrlkey) {          addusers(id);     } }

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
