An Amplitude-Distribution Analyzer
Abstract
Amplitude-distribution density, one of the important statistical properties of a signal, represents the relative probability of existence of different instantaneous signal levels. An automatic analyzer capable of rapid, moderately accurate computations was needed to determine this function for numerous recoded signal and noise samples an for quantitative comparison of their significant characteristics. Direct solution by any mechanical or electrical device involves scanning over the appropriate amplitude ranges with an integrating detector that has a response proportional to the total time that a given level is occupied by the signal. If results are to be absolutely accurate, integration must be performed for an infinitely narrow amplitude slice; but since this implies infinitely high detector sensitivity, all practical systems represent some compromise.
