Claim 1
Independent Claim
151 words
A PHASE DISCRIMINATOR CIRCUIT COMPRISING A SOURCE OF WAVE SIGNALS FREQUENCY MODULATED OVER AN OPERATING BAND OF FREQUENCIES, TWO SIGNAL CHANNELS COUPLED TO SAID SOURCE, A PHASE SHIFTING NETWORK IN ONE OF SAID CHANNELS FOR VARYING THE PHASE OF SAID WAVE SIGNAL IN ACCORDANCE WITH THE SIGNAL FREQUENCY, AND MEANS RESPONSIVE TO THE PHASE DIFFERENCE BETWEEN THE WAVE SIGNALS IN SAID TWO CHANNELS FOR VARYING THE OUTPUT VOLTAGE AS A GENERALLY LINEAR FUNCTION OF SAID PHASE DIFFERENCE OVER SAID FREQUENCY BAND, AND MEANS FOR IMPROVING THE LINEARITY OF SAID DISCRIMINATOR CIRCUIT OVER SAID FREQUENCY BAND, SAID MEANS INCLUDING A FIRST RESONANT CIRCUIT IN SAID NETWORK FOR MODIFYING THE WAVE SIGNAL PHASE AT ONE END OF SAID BAND, A SECOND RESONANT CIRCUIT IN SAID NETWORK FOR MODIFYING THE WAVE SIGNAL PHASE AT THE OTHER END OF SAID BAND, AND MEANS FOR PREDETERMINING THE PHASE SHIFT AT THE CENTER FREQUENCY OF SAID BAND.
