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
