WebNov 8, 2016 · The code in the answer gives exactly the same result as signal.lfilter (b, 1, data, zi=z). The zi is a matter of choice, yet it should ensure results [0] == data [0] (see lfilter_zi ). Without, or with z=zeros (b.size-1) results [0] will be close to 0. And I still argue we will always get 'strange' first values, as for the first values of ... WebFor this example we will downsample by 25 and create a new filter. R = 25; # how much to down sample by Fsr = Fs/25. # down-sampled sample rate xs = signal.resample (x, len (x)/25.) If we update the design parameters for the FIR filter the new response is.

Web$\begingroup$ lfilter is not necessarily minimum-phase, it can be anything depending on the filter coefficients, but in any case it is causal, which filtfilt is not. So the result of the comparison that filtfilt has zero delay, and lfilter always adds some delay is not exactly true, because filtfilt is non-causal in the first place. What actually matters is that filtfilt does not … WebAll Algorithms implemented in Python.
