Kaiser window filter from specification object
h = design(d,'kaiserwin')
h = design(d,'kaiserwin',Name,Value)
h = design(d,'kaiserwin') designs
a digital filter using a Kaiser window. For
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.
a warning when your filter order may be too low to design your filter
h = design(d,'kaiserwin',Name,Value) returns
a filter designed with the Kaiser window technique and with design
options specified as
To determine the available design options, use
designmethods with the specification
object and the design method as input arguments as shown.

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.
