For this example, set the Q factor for the filter to 35 and use it to specify the filter bandwidth. wo = 60/ (300/2); bw = wo/35; [b,a] = iirnotch (wo,bw); 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. This MATLAB function returns the numerator coefficients, num, and the denominator coefficients, den, of the digital notching filter with the notch located at w0 and the bandwidth at the –3 dB point set to bw.

This can be done using the conv function.

For this example we consider the following notch filter: H ( s ) = s 2 + 0 . 5 s + 1 0 0 s 2 + 5 s + 1 0 0 % Design a filter with a Q-factor of Q=35 to remove a 60 Hz tone from % system running at 300 Hz. Wo = 60/(300/2); BW = Wo/35; [b,a] = iirnotch(Wo,BW); If you replace the 60 with 50 Hz and then do: Y = filter(b,a,X) It should work (with X your data) View MATLAB Command. Design and plot an IIR notch filter that removes a 60 Hz tone (f0) from a signal at 300 Hz (fs). For this example, set the Q factor for the filter to 35 and use it to specify the filter bandwidth. wo = 60/ (300/2); bw = wo/35; [b,a] = iirnotch (wo,bw); how to remove 60hz noise from an ECG signal Learn more about ecg signal, notch filter, how to read ecg signal into matlab View MATLAB Command.

The Data Types and Code Generation panes are not available for blocks in the DSP System Toolbox™ Filter Designs library. This MATLAB function returns the numerator coefficients, num, and the denominator coefficients, den, of the digital notching filter with the notch located at w0 and the bandwidth at the –3 dB point set to bw. The fdesign.notch function returns a notch filter design specification object that contains the specifications for a filter, such as passband ripple, stopband attenuation, and filter order. Then, use the design function to design the filter from the filter design specifications object.
