Butterworth filter - Wikipedia

The Butterworth filter is a type of signal processing filter designed to have a frequency response as flat as possible in the passband. It is also referred to as a maximally flat magnitude filter. It was first described in 1930 by the British engineer and physicist Stephen Butterworth in his paper entitled "On the Theory of Filter Amplifiers".

BANDPASS_FILTER - ClimServ

With a Butterworth bandpass filter, frequencies at the center of the frequency band are unattenuated and frequencies at the edge of the band are attenuated by a fraction of the maximum value. The Butterworth filter does not have sharp discontinuities between frequencies that are passed and filtered.

13/12/2014· By the way - there is no bandpass of fifth order. The order is determined by the number pole pairs [correction: number of poles] (n=2,4,6..) - and it is not a simple task to design a Butterworth bandpass of order n=4 or n=6. Are you allowed to use a filter design program? This would be the best and easiest way for designing such a filter.
