phasez(hs)
phasez
returns the unwrapped phase response
based on the current filter coefficients. This section describes phasez
operation
for discretetime filters, multirate filters, and filter System objects.
For more information about optional input arguments for phasez
,
refer to phasez
in Signal Processing Toolbox™ documentation.
[
returns
the phase response phi
,w
]=phasez(hfilt
)phi
of the filter hfilt
and
the corresponding frequencies w
at which the function
evaluates the phase response. The phase response is evaluated at 8192
points equally spaced around the upper half of the unit circle.
[
returns
the phase response phi
,w
]=phasez(hfilt
,n
)phi
of the filter hfilt
and
the corresponding frequencies w
at which the function
evaluates the phase response. The phase response is evaluated at n
points
equally spaced around the upper half of the unit circle.
phasez(hfilt)
displays the
phase response of hfilt
in the Filter Visualization
Tool (FVTool).
