Dear colleagues.

For my final work on MSc thesis, I'm working with EMG signals. The
electronic that I've developed works quite right, but 50 Hz noise is a real
problem (enviroment noise). I did a program om matlab to calibrate device
(acquire noise) and then acquire the signal.

The question is how can I improve SNR given this signals? I'm trying
subtract the ARV value of noise to ARV value of emg signal, but seems don't

If anyone have any comment please let me know.

Thanks in advance.
