WebSep 25, 2024 · Basically, Hilbert transformers are, by definition, non-causal, always. Any zero-phase filter is non-causal. We can shift the impulse in time but the phase then becomes linear and not flat (a function of frequency). To be implemented, the input signal must be delayed by the amount that is half the length of the filter minus one ( N in this case).
