edited : have textbox in mainwindow value "db2012_2013" code of frame 1 :

    <frame  horizontalcontentalignment="stretch" loadcompleted="frsample_loadcompleted" navigating="frsample_navigating" verticalcontentalignment="stretch" x:name="frsample" background="{x:null}" margin="0,0,0,0" source="{binding selecteditem.xamlfilepath, elementname=categorytreeview, fallbackvalue=welcome.xaml, isasync=true}"/>

then when choose page open pass value of textbox in new page ... use value query ..

you can use datacontext , wpf binding feature.

you can set datacontext belong mainwindow. need pass data frame or ui component textbox?

<textbox name="textbox" text="text"></textbox> <frame datacontext="{binding elementname=textbox,path=datacontext}" background="aliceblue" width="200">

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
