摘要：

Side channel interference has been a problem in the standard (AM) broadcast band since the advent of radio broadcasting. The two major contributing factors are: 1) radiation of audio-frequency components greater than 5 kHz, and 2) receivers having poor selectivity characteristics. Other more or less controllable factors are overmodulation of the carrier and inherent distortion in the transmitter. This paper describes a method of greatly reducing the major source of side channel interference by limiting the transmission of audio-frequency components above 5 kHz.
