genphase

Fit single-input/single-output magnitude data with real, rational, minimum-phase transfer function

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.
