Abstract: A transmission separation filter designed as an all pass filter network which comprises two equal frequency filters whose partial filters have reciprocal characteristic functions and are symmetrically connected with respect to the input and output of the transmission separation filter. Two-port circuits are connected between respectively equal partial filters and may be embodied as transformers, reactance networks, distortion correctors or amplifiers, and are dimensioned such that the electrical properties of the entire network coincide with the electrical properties of the interconnected two-port circuits in the partial frequency ranges, with the exception of an additional phase. The partial filters have uneven characteristic functions and a 180* phase shifter is provided in one filter branch and the two-port circuit of the same branch is the dual of the respective two-port circuit interconnected in the other filter branch.

Abstract: A dividing filter network wherein two port circuits, such as transformers, reactance circuits, equalizers and amplifiers, are interconnected in each branch of a mirror-image arrangement, the two-port circuits being designed and constructed in such a way that the frequency characteristics of the entire network agrees with the predetermined frequency characteristics of the interconnected two-port circuits, except for an additional phase.

Abstract: A network consisting of an all-pass circuit which consists of two equal frequency separating networks whose partial filters have even characteristic functions reciprocal to one another of the degree 2n (n=1, 2, 3 . . . ) and in which between each two equal partial filters there are connected four-pole circuits which are dimensioned in such a way that the electrical properties of the entire network, except for one additional phase, agree with the prescribed electrical properties of the interposed four-pole circuits. The interposed four-pole circuits are constructed with respect to their transmission properties as equal all-pass or low-pass sections of which the one lying in the band-pass or low-pass path, is rendered a band stop circuit by quartz elements.
