WebMar 26, 2016 · You start with the voltage divider equation: The transfer function T (s) equals VC(s)/VS(s). With some algebra (including multiplying the numerator and denominator by s/R ), you get a transfer function that looks like a low-pass filter: You have a pole or corner (cutoff) frequency at s = –1/ (RC), and you have a DC gain of 1 at s = 0. WebThe frequency response of the Butterworth filter is maximally flat (i.e. has no ripples) in the passband and rolls off towards zero in the stopband. When viewed on a logarithmic Bode plot, the response slopes off linearly towards negative infinity.A first-order filter's response rolls off at −6 dB per octave (−20 dB per decade) (all first-order lowpass filters … gisha restaurant mitcham
