I'm doing a project to eliminate 60Hz of power supply from ECG signal and I want to implement by using equiripplr notch filter (Parks-McClellan). I found the (firgr) function and I tried to implement notch filter using it with fs=175Hz but I can't. Can someone help me. this my code: %%
f=0.01:0.05:1; % frequency range
a7=ones(1,20);
a7(1,14)=0; % all a7 ones except at 60Hz normalized at 0.658*pi
d={'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n' 'n'};
b7 = firgr(20,f,...
a7,d);
fvtool(b7);
