The LowPass Elliptic Even Filter

An even order low pass Elliptic filter. These filter are subject to un-equal termination resistors, If equal resistors are set, then the minimum ratio will be used.

After synthesis a frequency transformation can be carried out but the stop band with be shifted upwards, so a change of order maybe required
