Abstract

700,871. Impedance networks. GENERAL ELECTRIC CO., Ltd., and ASPIN, J. J. E. Jan. 24, 1952 [March 5, 1951], No. 5286/51. Class 40 (8) A bandpass electric filter circuit comprises a central filter section 1, consisting of lumped constant elements L1, L2, C1 and C2, connected between impedance transformers 2 and 3, the latter being resonant at a frequency within the pass band, and having characteristics such that the input and output impedances of the whole circuit are higher than those of section 1. As shown the impedance transformers are sections of coaxial line of length equal to one quarter of a wave length of some frequency within the pass band.
