Receivers AM input signals probability characteristics and quality estimation

摘要

Different structures of universal and automated integral monitoring systems (AIMS) for broadcasting are discussed. A procedure determining the probability characteristics of broadcasting receivers input signal levels is investigated, and useful statistic distribution laws are obtained. The results enable us to propose an integral quality estimation for an amplitude modulated broadcasting system operating in the 0.15 to 30 MHz frequency range. This method can be applied to various modulation methods and frequency ranges.
