WebApr 21, 2024 · To filter out the 1kHz noise, I am required to design using two Butterworth filters connected in parallel where one is a low pass and the other is a high pass Butterworth Filter. I have tried to notch out the 1kHz noise by setting the bandwidth to (+/-10Hz) of the 1kHz noise. WebApr 15, 2011 · Accepted Answer: Rob Graessle. I'm designing a simple 60 Hz butterworth notch filter like this. [b a] = butter (n, [59 61]./ (fs/2), 'stop'); When I use fvtool to look at the magnitude and phase response everything looks fine until I make n>=5, then both responses start to go all of the place. My magnitude response no longer looks like a notch. methimazole tablets 5mg for cats
