On the theory of filter amplifiers
WebOn the Theory of Filter Amplifiers.* By S. Butterworth, M.Sc. (Admiralty Research Laboratory). THE orthodox theory of electrical wave filters has been admirably … 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 … Ver mais 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 Ver mais A transfer function of a third-order low-pass Butterworth filter design shown in the figure on the right looks like this: A simple example of a Butterworth filter is the third-order low-pass design shown in the figure on the … Ver mais There are several different filter topologies available to implement a linear analogue filter. The most often used topology for a passive realisation … Ver mais 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 Ver mais 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 Ver mais Properties of the Butterworth filter are: • Monotonic amplitude response in both passband and stopband • Quick roll-off around the cutoff … Ver mais
