Claim 1
Independent Claim
180 words
A SYSTEM FOR ANALYSIS OF ELECTRIC SIGNALS GENERATED BY AND REPRESENTATIVE OF VIBRATIONS IN A VIBRATION SOURCE CONTAINING "ALMOST PERIODIC" OCCURRENCES COMPRISING A TRANSDUCER FOR CONNECTION WITH THE VIBRATION SOURCE TO PROVIDE A SUITABLE ELECTRICAL SIGNAL INCLUDING PULSES REPRESENTATIVE OF THE VIBRATIONS, A GATE CIRCUIT HAVING SIGNAL INPUT, GATE CONTROL AND OUTPUT TERMINALS AND CONNECTED AT ITS SIGNAL INPUT TERMINAL TO THE OUTPUT OF THE TRANSDUCER, A SWITCH CIRCUIT CONNECTED BETWEEN THE TRANSDUCER AND THE GATE CONTROL TERMINAL OF THE GATE TO PRODUCE A GATE SIGNAL OF PREDETERMINED DURATION A PREDETERMINED TIME AFTER RECEIVING A PULSE AT THE OUTPUT TERMINAL THE LAST PREVIOUS GATE SIGNAL IN ORDER TO PERMIT THE SIGNAL REPRESENTATIVE OF VIBRATIONS AT THE INPUT TERMINAL TO APPEAR AT THE OUTPUT TERMINAL OF THE GATE DURING THE SIGNAL OF PREDETERMINED DURATION, SAID SIGNAL OF PREDETERMINED DURATION BEING SUFFICIENTLY NARROW THAT STATISTICALLY THE PROBABILITY THAT A PULSE WOULD BE FOUND WITHIN A RANDOMLY OCCURRING INTERVAL OF SUCH PREDETERMINED DURATION IS LESS THAN ONE, AND MEANS COUPLED TO THE OUTPUT OF THE GATE FOR COUNTING PEAKS IN SAID LAST-MENTIONED OUTPUT.
