Abstract
IN the Record published in October by the Bell Telephone Laboratories, Inc., L. Weis gives a helpful discussion of the problem of transmission signals over telephone cables. Most radio broadcasts originate in the studios of the broadcasting companies, and are transmitted thence to the radio stations over high-quality programme circuits. Not infrequently the ‘pick-up’ point is at a distance from the studio and circuits to the studio must be provided over telephone ‘cable pairs’ not normally employed for broadcasting. With television broadcasts such remote pick-up points are also required, but the utilization of ordinary telephone circuits to link them to the television studio is more difficult because of the much wider band of frequencies employed, besides certain exacting requirements for television transmission. Because of the experimental state of television broadcasting at the present time, no arrangements for transmitting from these remote pick-up points have as yet been standardized.
