Currently, I have an audio file which is only 30 seconds and is corrupted with a tone of 0.8kHz. I have to design a low pass Butterworth filter in parralel with the high pass Butterworth filter to notch out the annoying interference. So may I know how to consider the parameters for the both of the Butterworth filters?
