Generate the phase associated with stable, minimum phase system using only its frequency response magnitude

Syntax

• resp = genphase(d) 
  

Description

genphase uses the complex-cepstrum algorithm to generate a complex frequency response resp whose magnitude is equal to the real, positive response d, but whose phase corresponds to a stable, minimum-phase function. The input, d, and output, resp, are frd objects.
