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
