Wide Band Transmission Over Balanced Circuits

Wide Band Transmission Over Balanced Circuits * By A. B. CLARK In a recent paper 1 amplifiers capable of handling frequency band widths of the order of 1,000 kc. or more are described, together with terminal apparatus for effectively utilizing these wide bands for telephone, telegraph and television purposes. The paper confines itself to the coaxial line structure for transmitting these wide frequency ranges but points out that broad-band transmission is also applicable to balanced conductor systems. The present paper discusses briefly some of the possibilities of the more familiar balanced circuits, circuits more or less as they now exist in the present plant being first considered, following which are circuits obtained by new construction. Wide-band transmission over balanced circuits offers interesting possibilities both for circuits in the present plant and for new construction.
