Designing a Notch Filter

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

Here is a video about the notch filter design. You could take a look at it.

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

Good luck.

Thanks for the response, but can you tell me what parameters I need to pass inside iirnotch() with Fs and notch frequncy given.

Thanks
