An Improved Pre-Emphasis Standard for A.M. Broadcasting

Document Thumbnail

The modified 75µs pre-emphasis standard proposed by the American NRSC could prove deleterious to AM broadcasting both in the quality received through the wanted channel and in the interference produced in the wanted channel by the adjacent channels. An alternative standard is proposed that could produce the improvements sought by the NRSC proposal with little or none of its ill effects, and could be implemented using a simple passive network. The optimum design of a 'whistle' filter for removing spurious products demodulated from the adjacent channel in a wide-band receiver is considered also.
