DETERMINATION OF INITIAL PHASE OF OSCILLATION OF NONSINUSOIDAL INTERMITTENT ELECTRIC SIGNAL HARMONIC

摘要

FIELD: instrumentation.SUBSTANCE: invention relates to instrumentation. Proposed method consists in application of special function based on electric signal f(t), its magnitude being defined by time t and variable angle ?. Note here that in compliance with this invention, said function is raised to positive power n larger than unity. Such value of angle ? is revealed for functional dependence computed by appropriate process whereat that functional dependence features maximum value. Said angle ? that satisfies that condition is a wanted value of initial phase ?of kharmonic oscillation. Data obtained in execution of one on computation procedures can be exploited for determination of amplitude of Aof kharmonic.EFFECT: higher accuracy of determination of initial phase ?of kharmonic oscillation in intermittent electric signal f(t).4 dwg
