'Constantk' FilterConstantk filters are sometimes used by themselves, and sometimes as a basis for the design of the other types. In the constantk filter, Z_{1} and Z_{2} are inverse elements; that is, if Z_{1}_{ }of Fig, 24 consists of inductance, then Z_{2} must consist of capacitance. That is,
where k is a constant independent of frequency. Because of the fact that the other filters are derived from it, the constantk filter is known as a "prototype."
