Phase correction system of electric signals

Claim 1

A PHASE CORRECTION SYSTEM SUITABLE FOR CORRECTING PHASE DEVIATIONS INDUCED DURING THE TRANSMISSION OF A PHASE MODULATED ELECTRIC SIGNAL INCLUDING AT LEAST SEVERAL CYCLES OF A REFERENCE PHASE WAVE OF CONSTANT AMPLITUDE, COMPRISING, A PHASE DETECTOR STAGE, A PHASE MODULATOR STAGE, A STABLE PHASE REFERENCE SIGNAL SOURCE, SAID PHASE DETECTOR STAGE INCLUDING AT LEAST A FIRST AND A SECOND SYNCHRONOUS DETECTOR FOR SYNCHRONOUS DETECTION ON TWOPHASE QUADRATURE AXES AND A FIRST 90* PHASE SHIFTER, SAID PHASE MODULATOR STAGE INCLUDING AT LEAST A FIRST AND A SECOND DOUBLY BALANCED MODULATOR FOR AMPLITUDE MODULATION ON TWO-PHASE QUADRATURE AXES AND A SECOND 90* PHASE SHIFTER, MEANS FOR APPLYING SAID PHASE MODULATED ELECTRIC SIGNAL DIRECTLY TO EACH OF SAID SYNCHRONOUS DETECTORS, SAID STABLE PHASE REFERENCE SIGNAL SOURCE CONNECTED DIRECTLY TO SAID FIRST SYNCHRONOUS DETECTOR AND THROUGH SAID FIRST 90* PHASE SHIFTER TO SAID SECOND SYNCHRONOUS DETECTOR FOR APPLYING A STABLE REFERENCE SIGNAL THERETO, SAID SYNCHRONOUS DETECTORS PRODUCING A PLURALITY OF FIRST ERROR SIGNALS ON TWO-PHASE QUADRATURE AXES CORRESPONSING TO THE PHASE DIFFERENCE BETWEEN THE PHASE OF THE REFERENCE PHASE WAVE INCLUDED IN SAID PHASE MODULATED ELECTRIC SIGNAL AND THE PHASE OF SAID STABLE PHASE REFERENCE SIGNAL, MEANS FOR APPLYING SAID PHASE MODULATED ELECTRIC SIGNAL DIRECTLY TO SAID FIRST DOUBLY BALANCED MODULATOR AND THROUGH SAID SECOND 90* PHASE SHIFTER TO SAID SECOND DOUBLY BALANCED MODULATOR, SAID SECOND SYNCHRONOUS DETECTOR CONNECTED TO SAID FIRST DOUBLY BALANCED MODULATOR FOR APPLYING SAID FIRST ERROR SIGNALS THERETO WHEREIN SAID PHASE MODULATED SIGNAL IS AMPLITUDE MODULATED, SAID FIRST SYNCHRONOUS DETECTOR CONNECTED TO SAID SECOND DOUBLY BALANCED MODULATOR APPLYING ERROR SIGNALS THERETO WHEREIN SAID 90* PHASE SHIFTED ELECTRIC SIGNAL IS AMPLITUDE MODULATED, AND MEANS FOR COMBINING BOTH OF SAID AMPLITUDE MODULATED SIGNALS AND OBTAINING RESULTANT OUTPUTS THEREFROM.
