The report is the result of an investigation to 1 determine a satisfactory parameter to describe the interference susceptibility of solid-state components, 2 determine suitable solid-state components to be used as protective devices to reduce RFI susceptibility, and 3 determine the RFI and operational characteristics of signal-processing techniques to permit the best choice, in a given interference environment, consistent with satisfactory operational characteristics. The third-order intermodulation coefficient is shown to be the most suitable measure of RFI performance. A simple technique for measuring the parameter as well as experimental results are described. Three types of limiters are discussed and it is shown that the ferrite limiter generally has the characteristics most desirable in a device for RFI susceptibility reduction. Passive frequency filtering is also considered. Author
