This book is a gentle introduction to digital filters, … The Butterworth filter is a type of signal processing filter designed to have a frequency response that is 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 … See more Butterworth had a reputation for solving very complex mathematical problems thought to be 'impossible'. At the time, filter design required a considerable amount of designer experience due to limitations of the See more A transfer function of a third-order low-pass Butterworth filter design shown in the figure on the right looks like this: See more There are several different filter topologies available to implement a linear analogue filter. The most often used topology for a passive realisation … See more Properties of the Butterworth filter are: • Monotonic amplitude response in both passband and stopband • Quick roll-off around the cutoff frequency, which improves with … See more The frequency response of the Butterworth filter is maximally flat (i.e. has no ripples) in the passband and rolls off towards zero in the stopband. When viewed on a … See more Like all filters, the typical prototype is the low-pass filter, which can be modified into a high-pass filter, or placed in series with others to form band-pass and band-stop filters, and higher order versions of these.
