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