zpell(1)

NAME
zpell - lowpass elliptic filter

CALLING SEQUENCE
[zeros,poles,gain]=zpell(epsilon,A,omegac,omegar)

PARAMETERS

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

DESCRIPTION
Poles and zeros of prototype lowpass elliptic filter. gain is the gain of the filter
