WebApr 6, 2024 · Filter Design – Butterworth Low Pass. Find the order of an active low pass Butterworth filter whose specifications are given as: Amax = 0.5dB at a pass band frequency ( ωp) of 200 radian/sec (31.8Hz), and … WebButterworth filters are termed maximally-flat-magnitude-response filters, optimized for gain flatness in the pass band. The attenuation is –3 dB at the cutoff frequency. Above the cutoff frequency, the attenuation is –20 dB/decade/order. The transient response of a Butterworth filter to a pulse input shows moderate overshoot and ringing.
