A Statistical Technique for the Treatment of Rarely Occurring Impulsive Noise

This treatment of rarely occurring impulsive noise is based upon the development of probability distributions for the peaks of impulses incident on a receptor data bus. Monitoring equipment designed to fit in restricted shipboard conditions was used to take long-term measurements of the common-mode voltage levels on data bus lines on board two ships. Impulses registered at the monitoring point were seen to be clustered in the form of bursts. Damped ringing of unterminated cable shields was put forward as one of the main mechanisms causing impulse clustering. The measured results were compared with the theory and excellent matches were achieved.
