The log-magnitude and phase, or real and imaginary parts of the Fourier transform of a minimum phase causal signal are related through Hilbert transform. These relations are extended for complex data. The method to stabilize an IIR Complex Coefficient filter, through the process of converting a mixed phase system into a minimum phase system, is discussed. © 1991.
