Hi,
I am using Ads1298pdk and its pc software to obtain EMG signals and process them. I am getting a lot of power noise at 50 Hz and its harmonics and I need to minimize it somehow. Now I know there are notch filters at 50/60 Hz but they don't work to solve the problem. I have two questions, first is can I change the sampling rate of ads1298 from software? If yes how? Second thing is why notch filters implemented in software aren't working on signals.
A screenshot of power noise corrupted signal is attached.
Regards,
Abdullah
