METHOD OF DETECTION OF SINE SIGNAL PARAMETERS Russian patent published in 2015 - IPC H03D3/02 

FIELD: radio-engineering, communication.

SUBSTANCE: method of detection of sine signal parameters is characterized in that phase of detected signal is determined, results obtained in the processing channels of main and reference sine signals are compared, first channel voltage is obtained from input oscillation in channel by means of multiplication by itself, and second channel voltage is received by differentiation and integration, then multiplication of integrated and differentiated signals, at that first output voltage of the appropriate channel is proportional to amplitude of the detected signal, and is determined by extracting of root of square of the detected amplitude, the second output voltage of the appropriate channel proportional to frequency of the detected signal is determined as ratio of channel differentiated signal to square root of difference of square of amplitude and first channel voltage, the third output voltage proportional to phase is determined as difference of integrals of second output voltage of main and reference channels.

EFFECT: reduced time of detection of sine signal parameters in wide range of frequencies without limitation of the frequency deviation.
