zerophase
returns the zerophase response
based on the current filter coefficients. This section describes common zerophase
operation
with discretetime and multirate filters. For more input options,
refer to zerophase
in Signal Processing Toolbox™ documentation.
[
returns the instantaneous
zerophase response hr

)hr
and the frequencies w
in
radians at which zerophase
evaluated the response.
The zerophase response is evaluated at 8192 points equally spaced
around the upper half of the unit circle.
