Abstract
460,355. Impedance networks. SIEMENS & HALSKE AKT.-GES. June 13, 1936, No. 16547. Convention date, June 14, 1935. [Class 40 (iii)] A network is so designed that its phase constant varies with frequency while both its characteristic impedance and its attenuation constant are independent of frequency. In the case of a lattice network having line and lattice impedances R1' R2, or an equivalent bridged-T network, Fig. 2 (not shown), the impedances R1, R2 must be inverse since the characteristic impedance Z is real and equal to #(R1R2)' and in order that the attenuation constant may be independent of frequency the impedance R1 is, according to the invention, given the forms (C1 + jd1#) /(C2 + jd2#) where # is a function of the frequency and C1d1/C2d2=Z<2>. A form of R1 for which # is equal to the pulsatance p is shown in Fig. 3, where W<2>R/ (W+R)=Z<2>. A form of R1 for which #= (pL - 1 /pC) is shown in Fig. 4, where the five impedance elements are connected by a single equation, and R, R<1> may be the resistances inherent in the reactances. R1 having been chosen, R2 is given the form inverse to it.
