Fitting graphs and numerical tables for a single parameter representation of the shape of programme sound signal distributions

In order to represent the statistical character of a sound signal simply and with a single parameter, numerical tables and graphs of theoretical distributions for the estimation of a parameter called the shape parameter of the distribution are presented. The theoretical distributions are based on a statistical model of broadcast signals which was derived from the analysis of variations in measured distribution. The statistical functions dealt with are PDFs (probability density functions) and CDFs (cumulative distribution functions) for instantaneous amplitude and power, for RMS-valued intensity fluctuations, and for one-minute mean powers and peak powers. A list of the values of the shape parameter estimated for CCIR data is given, from which almost all the CCIR data can be reproduced by using the theoretical distribution curves and the numerical tables presented
