zpell
lowpass elliptic filter
Syntax
[zeros,poles,gain]=zpell(epsilon,A,omegac,omegar)
Arguments
- 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 angular frequency in radians per second
- omegar
real : stop band cut-off angular frequency in radians per second
- 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
