Member of the filter design class.

Syntax

[z, p, k] = ellipap(n, r1, r2)

Generates the zeros, poles, and gain of an analog Elliptic lowpass filter of the order specified by n.

Name	Description
n	Specifies the filter order. n is a nonnegative integer.
r1	Specifies the decibel value of the peak-to-peak ripple in the passband. r1 is a real number.
r2	Specifies the decibel value of the minimum stopband attenuation. r2 is a real scalar.

Name	Description
z	Returns the zeros of the filter. z is a vector.
p	Returns the poles of the filter. p is a vector.
k	Returns the gain of the filter. k is a real number.

[Z, P, K] = ellipap(5, 0.1, 60)
