hi,
I have eeg signal with noise.then i have used tv filter to remove noise. but the changes in the output i would like to be visible.for that i would like to calculate snr. Do anyone have matlab code for that.
 

You can model stray hum, random thermal noise, electric field noise and galvanic skin response.

You can also use a TV 50/60Hz common mode filter to reduce hum.

But each user has unique conditions. What do you get?
