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