Abstract

Different methods of measurement of amplitude-modulated signal parameters are proposed and analyzed. The methods are based on scanning the instantaneous signal values with the aid of program-controlled dc voltage levels varying in uniform and nonuniform steps. Block diagrams of modulation meters and their estimated accuracy of amplitude-modulation factor measurements are given.
