Member of the filter design class.

Syntax

[n, w, b, t] = kaiserord(f, a, d)

[n, w, b, t] = kaiserord(f, a, d, fs)

Estimates the order of a Kaiser window.

Name	Description
f	Specifies the band edge frequencies. The length of f is twice the length of a minus 2. f is a vector in ascending order between 0 and fs/2.
a	Specifies the desired amplitude of the FIR filter. a is a vector of zeros and ones.
d	Specifies the allowable ripples for each band. d is a vector. length(d) must equal length(a).
fs	Specifies the sampling frequency. The default value is 2.

Name	Description
n	Returns the approximate order.
w	Returns the normalized frequency band edges.
b	Returns the Kaiser window parameter, beta.
t	Returns the type of the FIR filter.

f = [1500, 1700, 2000, 2100, 2300, 3000];
a = [1, 0, 1, 0];
d = [0.01, 0.1, 0.01, 0.1];
fs = 10000;
[n, w, b, t] = kaiserord(f, a, d, fs)
