A Method of Detecting Significant Sources of Intermodulation Interference.

摘要

An accurate knowledge of lowest orders is shown to be important for locating significant sources of intermodulation interference signals. A practical,reliable method is presented for calculating the lowest order occurring on the frequency of any intermodulation signal observed to be strong enough to threaten low-error-rate reception. A hypothetical example involving two local transmit frequencies is described. The method is found to represent a major extension in applicability and ease of use over previous calculations,which were awkward and unsatisfactory for field use. (Author)
