Abstract
The present invention phase coherent crossover incorporates a method and apparatus for providing phase coherent crossover (PCC) signals. The PCC method and apparatus involve the utilizing of an all-pass filter for receiving an input signal and producing an all-pass signal, and a partial-pass filter also receiving the input signal and producing a partial-pass signal at a partial-pass output. The PCC method and apparatus further involve the combining of the partial-pass signal produced by the partial-pass filter with the all-pass signal produced by the all-pass filter to produce an opposite partial-pass signal at an opposite partial-pass output.
