Hello,
I'd like to design a notch filter with Fs=22050Hz, frequency=60Hz sinusoidal signal. Can someone please tell me what parameters to pass inside the notch filter function?
Also, I have a voice signal saved as .wav file in my computer, and I want to mix it with the above 60Hz sine signal. Can someone help me with both my queries? I've been trying a few ways, but couldn't find the result.
Thanks

% The signal processing toolbox of MATLAB has:
iirnotch()
% Import your wav file with:
[y,Fs] = audioread('AUDIO_FIle.wav');
%
Good luck.
