Hello group, I have a question regarding minimum phase system and causal
For a minimum phase system, the measured discrete frequency domain data
are given. To remove the measurement noise, I use the
-hilbert(log(abs(H(F))) to generate the phase of the system, and then get
time domain waveform through h(t) = IFFT(abs(H(F))* exp(j*phi(F))). I found
h(t) is not causal.
From the text book, it says the minimum phase system is causal and
I don't understand it's not causal in my case.
thanks a LOT and admiration to anyone able and willing to answer,
