This section is intended primarily for rapid dissemination of brief reports on new research results in technical areas of interest to IEEE members. Contributions are reviewed immediately, and acceptance is determined by timeliness and importance of the subject, and brevity and clarityof the presentation. Research letters must contain a clear concise statement of the problem studied, identifv new results, and make evident their utility, importance, or relevance to electrical engineering. Key to related literature must be given.
Contributions shouldbe submitted in triplicateAbstract-A digital computer simulation has been used in an effort to define the RF bandwidth needed for good transmission in F M systems in terms of given amounts of interchannel distortion. The computed results have been converted into a relationship that is similar to Carson's rule but perhaps more meaningful.
