From scipy.signal import argrelmax
WebDec 5, 2015 · 2 Answers. I think that a non-linear filter will give you a result that comes closer to what you expect. One of the simplest non-linear filters is a median filter, which can remove noise while preserving jumps. The figure below shows your data and the outputs of a median filter with a window length of 20 samples. WebThe signal x is upsampled by the factor up, a zero-phase low-pass FIR filter is applied, and then it is downsampled by the factor down. The resulting sample rate is up / down times the original sample rate. Values beyond the boundary of the signal are assumed to be zero during the filtering step. Parameters x array_like. The data to be ...
