FIELD: measurement equipment.
SUBSTANCE: invention is related to the field of information processing system and measurement equipment. For initial and reference signal provided by counts of instantaneous values in one and the same moment of time, joint solution points are found in case of various circular frequencies of reference signal. Besides reference and initial signal are specified by counts of instantaneous values, Derivative is identified for initial signal. Then area of volt-ampere characteristic is defined for point of joint solution of derivative in initial and reference signals. Maximum value of volt ampere characteristics area is identified at various phases. Also for points of joint solution of initial and reference signals, area of volt-ampere characteristics is defined. Maximum value of amplitude is detected at various phases. Signal spectral composition is based on values of amplitudes, circular frequency of reference signal and phase. These values are either transferred to computer or brought to display.
EFFECT: expanded arsenal of facilities with the same purpose.
