Impulse noise in communication receivers and its reduction

MetadataShow full item record
The material presented in this paper is based partly on a survey of the literature on noise and partly on experience and information acquired in the laboratory working on a specific noise reduction problem. The entire field of nosie is obiously too broad for adequate treatment in a paper of this type. Consequently, emphasis has been placed on impilse noise reduction systems in communication receivers, i.e., in receivers operating in the frequency range of roughly 1 to 20 mcs. Laboratory work on a noise blanking system was done in the radio interference laboratory of the Lightning and Transients Research Institute, Minneapolis, Minnesota. Development work on the blaning systems is being carried out under an Office of Naval Research contract sponsored by the Bureau of Aeronautics. The author was assigned the task of developing and testing a new type of discriminator for the noise blanking unit based on an original idea by M. Newman of the Lightning and Transients Research Institute. As a result of this development work, a complete blanking unit employing the new discriminator was constructed. It is regretted that insufficient time was available to completely test and evaluate this new system. Preliminary tests, however, indicated that scheme has very definite possiblities and warrants further investigation.
