I have been removing line frequency using the notch filter so far and it
works fine. However, my data shows lines at 120 and 180 Hz as well (line
frequency in US is 60Hz).
So I tried
cfg.lnfreq = [60 120];
It is accepted, but it does not work. Infact now, even the 60Hz notch
filtering does not work.
Is there a way to implement both?
