y = filtfilt(b,a,x) performs zero-phase digital filtering by processing the input data x in both the forward and reverse directions. After filtering the data in the forward direction, the function reverses the filtered sequence and runs it back through the filter. The result has these characteristics:
Zero phase distortion.
A filter transfer function equal to the squared magnitude of the original filter transfer function.
A filter order that is double the order of the filter specified by b and a.
filtfilt minimizes start-up and ending transients by matching initial conditions. Do not use filtfilt with differentiator and Hilbert FIR filters, because the operation of these filters depends heavily on their phase response.
y = filtfilt(sos,g,x) zero-phase filters the input data x using the second-order section (biquad) filter represented by the matrix sos and the scale values g.
