Amplitude density probability computer

Claim 1

A COMPUTER FOR COMPUTING AMPLITUDE DISTRIBUTION OF A RELATIVELY RAPIDLY RANDOMLY AMPLITUDE VARYING SIGNAL, COMPRISING A SOURCE OF RELATIVELY SLOWLY VARYING SAWTOOTH COMPARISON SIGNAL, SAID SAWTOOTH COMPARISON SIGNAL HAVING A RANGE OF AMPLITUDE AT LEAST CO-EXTENSIVE WITH AMPLITUDES OF INTEREST IN SAID RELATIVELY RAPIDLY RANDOMLY AMPLITUDE VARYING SIGNAL, THE RATE OF RISE OF SAID SAWTOOTH COMPARISON SIGNAL BEING SUFFICIENTLY SLOW TO PERMIT STATISTICAL SAMPLING OF THE AMPLITUDES OF SAID RELATIVELY RAPIDLY RANDOMLY AMPLITUDE VARYING SIGNAL, A LIMITING DIFFERENCE AMPLIFIER RESPONSIVE TO SAID RELATIVELY RAPIDLY RANDOMLY AMPLITUDE VARYING SIGNAL AND TO SAID SAWTOOTH COMPARISON SIGNAL FOR GENERATING CONSTANT AMPLITUDE DIFFERENCE SIGNALS ONLY DURING OCCURRENCE OF A PREDETERMINED AMPLITUDE RELATION BETWEEN SAID RELATIVELY RAPIDLY RANDOMLY AMPLITUDE VARYING SIGNAL AND SAID SAWTOOTH COMPARISON SIGNAL, MEANS RESPONSIVE TO THE SIGNAL DERIVING FROM SAID AMPLIFIER FOR INTEGRATING SAID CONSTANT AMPLITUDE DIFFERENCE SIGNALS OVER TIMES FOR WHICH SAID SAWTOOTH COMPARISON SIGNAL IS SUBSTANTIALLY CONSTANT WHILE SAID RELATIVELY RAPIDLY RANDOMLY AMPLITUDE VARYING SIGNAL VARIES THROUGH A RANGE OF AMPLITUDES AND A DIFFERENTIATING CIRCUIT COUPLED IN CASCADE WITH SAID MEANS FOR INTEGRATING.
