zpell — lowpass elliptic filter
[zeros,poles,gain]=zpell(epsilon,A,omegac,omegar)
| epsilon | : real : ripple of filter in pass band (0<epsilon<1) |
| A | : real : attenuation of filter in stop band (A>1) |
| omegac | : real : pass band cut-off frequency in Hertz |
| omegar | : real : stop band cut-off frequency in Hertz |
| zeros | : resulting zeros of filter |
| poles | : resulting poles of filter |
| gain | : resulting gain of filter |
Poles and zeros of prototype lowpass elliptic filter. gain is the gain of the filter
