DETERMINATION OF INITIAL PHASE OF OSCILLATION OF NONSINUSOIDAL INTERMITTENT ELECTRIC SIGNAL HARMONIC Russian patent published in 2014 - IPC G01R29/00 

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 θ. Note here that in compliance with this invention, said function is raised to positive power n larger than unity. Such value of angle θ is revealed for functional dependence computed by appropriate process whereat that functional dependence features maximum value. Said angle θ that satisfies that condition is a wanted value of initial phase ψ_(k) of k^th harmonic oscillation. Data obtained in execution of one on computation procedures can be exploited for determination of amplitude of A_m(k) of k^th harmonic.

EFFECT: higher accuracy of determination of initial phase ψ_(k) of k^th harmonic oscillation in intermittent electric signal f(t).
