CNAME address in apache configuration -

-

i have multiple domain map server's subdomain. example

www.xyz.com -> goo.myserverdomain.com www.lmn.com -> fb.myserverdomain.com www.abc.com -> twt.myserverdomain.com

i mapping using cname in each domain. @ server end, want resolve server subdomain. want configure 

servername myserverdomain.com serveralias *.myserverdomain.com proxypass / http://<ip>:8780/(goo/fb/twt ...)

when configuration, apache not recognize virtual host , show first default one. seems getting host name. how resolve myserverdomain address in configuration. please help

it not matter how domain mapping done. apache not know , web browser not care. reacts on line "host:" send in header.

to enable virtual name solving, need set

namevirtualhost ...

for each ip+port combination or '*' all.

usually when starting, apache tell you have virtual hosts, no proper name switching.

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
