phasez

System object: dsp.BiquadFilter
Package: dsp

Unwrapped phase response

Syntax

[phi,w] = phasez(H)
[phi,w] = phasez(H,n)
[phi,w] = phasez(H,Name,Value)
phasez(H)

Description

[phi,w] = phasez(H) returns the 8192–element phase response vector phi, and the corresponding frequencies w in radians/sample.

[phi,w] = phasez(H,n) returns the n-element phase response vector phi, and the corresponding frequencies w in radians/sample, using n samples.

[phi,w] = phasez(H,Name,Value) returns the phase response and the corresponding frequencies, with additional options specified by one or more Name, Value pair arguments.

phasez(H) uses FVTool to plot the phase response of the filter System object™ H.
