# iir_ellipticzpk

Version:

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

## Syntax

[z, p, k] = iir_ellipticzpk(n, r1, r2)
Legacy name: ellipap

## n

Filter order. n is a positive integer.

## r1

Decibel value of the peak-to-peak ripple in the passband. r1 is a real number.

## r2

Decibel value of the minimum stopband attenuation. r2 is a real scalar.

## z

Zeros of the filter. z is a vector.

## p

Poles of the filter. p is a vector.

## k

Gain of the filter. k is a real number.

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