php - Zend Framework 2 with Doctrine 2 custom validation and object structure -

-

what proper class , object structure supports custom validations in zf2 , doctrine2?

for example, have simple user entity, , wish check if email provided unique. validation requires access entitymanager can't done entity in getinputfilter method.

what proper application structure support that?

in current workflow user's name validated in controller, seems kind of wrong. relevant objects , scripts view: edituser.phtml controller: usercontroller.php - gets user post input , serves - creates validator, , checks if ($validator->isvalid()) entity: user.php - performs other basic property validation, cannot perform isunique

if need create custom validation class, object instantiate , use it? absolutely need have separate user business model apart entity, have healthy oop structure ?

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
