METHOD FOR GENERATION OF SIGNALS WITH ARBITRARY SHAPES Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: method involves recovery of analog signal from its digital values by means of its approximation by local spline function of n power. This is achieved by following procedure. M adjacent values of input signals, which correspond to instantaneous values of generated signal, are multiplied by corresponding constant weights, converted to analog form by means of digital-to-analog converter. Stepwise analog signal from output of digital-to-analog converter is integrated n times. Number of M and values of constant weights is determined according to method of approximation. Invention specification lists possible implementation of said method using local spline of second power. Values of constant weights and number M are given for this implementation. EFFECT: increased precision. 2 dwg
