Abstract :
Equipment for handling frequency band widths of the order of 1,000,000 cycles or more for telephone, telegraph, and television purposes was described in a recent Institute paper “Wide Band Transmission Over Coaxial Lines.” This previous paper confines itself to the coaxial line structure, 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 essentially as they now exist in the present plant being first considered, following which are considered circuits obtained by new construction. Wide band transmission over balanced circuits offers interesting possibilities both in the present plant and for new construction.
