Title: Improvements relating to the measurement of cross-talk in telephone lines
IPC: H04B3/46
Filed: 1927-11-24
Abstract: 281,311. Viard, G. Nov. 25, 1926, [Convention date]. Artificial lines.-A variable attenuation network for use as a crosstalk meter, comprising series resistance R<1>, R", and shunt resistance r, is designed to have a large inlet impedance which is only slightly altered when the attenuation is varied and a variable outlet impedance Zh which remains unaltered as the attenuation is varied. In the embodiment shown, R' is divided into two portions, R<1>2 which is small and is varied independently to give a fine adjustment of the attenuation and R<1>1 which is varied simultaneously with r by a slider K<1> for making large adjustments in such a way that R<1>1 + r which has a large value. is kept constant. The inlet impedance (R<1> + r) is thus approximately constant. R<11> is similarly divided into a portion R<11>2 which is adjusted initially to give the desired impedance Zb (approximately R<11> + r) and a portion R<11>1 variable as the attenuation is adjusted by the slider K, so that r + R<11>, is kept constant. Formulµ are given for calculating the resistances necessary to produce a given attenuation. The T-network may be replaced by an I arrangement in which half of R' is connected to each end of a resistance of value 2r and half R" is connected to each end of a similar resistance, the resistances 2r being bridged by a pair of sliders moving simultaneously in opposite directions to vary the attenuation.
