kaiserwin
R2026bKaiser window filter from specification object
Syntax
h = design(d,"kaiserwin")
h = design(d,"kaiserwin",Name=Value)
Description
h = design(d,"kaiserwin") designs a digital filter
using a Kaiser window. For kaiserwin to work
properly, the filter order in the specifications object must be
even. In addition, higher order filters (filter order greater
than 120) tend to be more accurate for smaller transition
widths. kaiserwin returns a warning when your
filter order may be too low to design your filter
accurately.
h = design(d,"kaiserwin",Name=Value) returns a filter
designed with the Kaiser window technique and with design
options specified as name-value arguments.
To determine the available design options, use designmethods with the
specification object and the design method as input arguments as shown.

system. For example, to get specific information about using
kaiserwin with
d, the specification object,
enter the following at the MATLAB® prompt.
help(d,"kaiserwin")
Examples
Design a direct-form FIR filter starting from the default lowpass filter specification object. Use a Kaiser window for the design. Visualize the magnitude response.
d = fdesign.lowpass;
Hd = design(d,"kaiserwin");
