WebApr 28, 2015 · I read the source code of a few Java implementations of Butterworth, but all of them appeared to assume a constant sample rate. Is there a way to implement Butterworth that allows for a variable sample rate? Or should I interpolate the accelerometer data to obtain a constant sample rate? If you answer with math, please … Web4. BUTTERWORTH FILTER The Butterworth filter has a maximally flat response that is, no passband ripple and roll-off of minus 20db per pole. It is “flat maximally magnitude” filters at the frequency of jω= 0, as the first 2N - 1 derivatives of the transfer function when jω = 0 are equal to zero [5]. The phase response of the
