Electrical phase meter and amplitude comparator

Claim 1

APPARATUS FOR THE MEASUREMENT OF THE TIME DELAY BETWEEN TWO SINUSOIDAL SIGNAL, COMPRISING IN COMBINATION: FIRST AND SECOND INPUT MEANS FOR RESPECTIVELY RECEIVING SAID TWO SINUSOIDAL SIGNALS; A TIME BASE SOURCE GENERATING A SERIES OF TIMING PULSES FOR ESTABLISHING A PREDETERMINED PER UNIT TIME INTERVAL; A FIRST TRIGGER CIRCUIT INCLUDING AMPLITUDE LEVEL SENSING MEANS COUPLING TO SAID INPUT MEANS AND SAID TIME BASE SOURCE FOR GENERATING A FIRST PULSE SEQUENCE IN ACCORDANCE WITH SAID TIMING PULSES WHENEVER THE FIRST OF SAID TWO SINUSOIDAL SIGNALS EXCEEDS A FIRST PREDETERMINED AMPLITUDE LEVEL; A SECOND TRIGGER CIRCUIT ALSO INCLUDING AMPLITUDE LEVEL SENSING MEANS COUPLED TO SAID SECOND INPUT MEANS AND SAID TIME BASE SOURCE FOR GENERATING A SECOND PULSE SEQUENCE IN ACCORDANCE WITH SAID TIMING PULSES WHENEVER THE SECOND OF SAID TWO SINUSOIDAL SIGNALS EXCEEDS A SECOND PREDETERMINED AMPLITUDE LEVEL; LOGIC CIRCUIT MEANS COUPLED TO SAID FIRST AND SAID SECOND TRIGGER CIRCUIT AND SAID TIME BASE SOURCE FOR DETERMINING, WITHIN THE TIME THAT ONE OF SAID FIRST AND SECOND PREDETERMINED AMPLITUDE LEVELS ARE EXCEEDED, THE OCCURRENCE OF SAID FIRST PULSE SEQUENCE AND THE NONOCCURRENCE OF SAID SECOND PULSE SEQUENCE AND SUBSEQUENTLY THE OCCURRENCE OF SAID SECOND PULSE SEQUENCE AND THE NON-OCCURRENCE OF SAID FIRST PULSE SEQUENCE; AND PULSE COUNTER MEANS COUPLED TO SAID LOGIC CIRCUIT MEANS FOR COUNTING THE TOTAL NUMBER OF PULSES RESULTING FROM SAID LOGIC CIRCUIT MEANS, SINCE BY DIVIDING SAID TOTAL NUMBER OF PULSES BY TWO TO AVERAGE THE PULSE COUNT AND BY KNOWING THE PER UNIT TIME INTERVAL OF SAID SERIES OF TIMING PULSES, THE TIME DELAY BETWEEN SAID TWO SINUSOIDAL SIGNALS CAN BE DETERMINED THEREBY.
