An efficient method for designing doubly terminated ladder filters in which reactive components have freely assignable losses is described. The method uses partial knowledge of the driving‐point impedance of such filters to generate a set of algebraic equations which are easily solved using a computer program. An example of the application of the method to the design of an active filter is included.
