AB  - A class of crossover systems is described which produce null responses in their high-pass and low-pass outputs at frequencies close to the transition crossover frequency. As a result, both outputs have a high initial rate of attentuation in their stopbands, while the sum of their output has a flat all-pass response. When the nulls are moved to very high and low frequencies, the transfer functions degenerate into Butterworth functions for odd order, and into Linkwitz-Riley functions, for even order. Active and passive realization are presented. The work is the subject of a patent application.
