Web总结. 1、巴特沃斯（Butterworth）滤波器是一种具有最大平坦幅度响应的低通滤波器，保证了信号的原始值，不会因为滤波被衰减。. 2、巴特沃斯滤波器的性能明显优于一阶低通滤 … WebThe Butterworth filter is a type of signal processing filter designed to have a maximally flat frequency response (having no ripples) on the pass-band and rolls off towards zero in the stop-band. It is also referred to as a maximally flat magnitude filter and offers the smoothest possible curve of any class of filter of the same order.
