Web17 de out. de 2024 · Filter Butterworth (Maximally Flat) Butterworth Filter adalah salah satu jenis signal processing yang dirancang untuk menghasilkan frekuensi respon yang sedatar mungkin pada passband. Jenis filter ini pertama kali diperkenalkan pada 1930 oleh fisikawan Inggris Stephen Butterworth, dalam paper yang berjudul “On the Theory of … 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 "On the Theory of Filter Amplifiers".
