Syntax
[z, p, k] = iir_ellipticzpk(n, r1, r2)
Legacy Name: ellipap
Description
Generates the zeros, poles, and gain of an analog Elliptic lowpass filter of the order specified by n.
Inputs
| 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. |
Outputs
| 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. |
