System for quantizing intelligence according to ratio of outputs of adjacent band-pass filters

Claim 1

A SYSTEM FOR CHANNELIZING ACCORDING TO FREQUENCY SIGNALS WHICH MAY HAVE ANY FREQUENCY WITHIN A PREDETERMINED BAND OF INTEREST COMPRISING, IN COMBINATION, A PLURALITY OF BAND PASS FILTERS EACH HAVING INPUT AND OUTPUT TERMINALS AND RESPECTIVELY RESPONSIVE TO FREQUENCIES IN SUCCESSIVE ADJACENT SUB-BANDS OF SAID BAND OF INTEREST AND HAVING SIMILAR PASS-BAND CHARACTERISTICS, THE PASSBAND CHARACTERISTIC OF EACH OF SAID FILTERS CROSSING OVER THE CHARACTERISTICS OF THE TWO FILTERS ADJACENT THERETO TO THEREBY DEFINE A PLURALITY OF ADJACENT CHANNELS OF A WIDTH DETERMINED BY THE SPACING BETWEEN THE POINTS OF CROSS-OVER OF ADJACENT PASS-BAND CHARACTERISTICS, ANY TWO ADJACENT FILTERS BEING OPERATIVE TO PRODUCE OUTPUT SIGNALS OF EQUAL AMPLITUDES IN RESPONSE TO AN APPLIED SIGNAL HAVING A FREQUENCY FALLING AT THE POINT OF CROSS-OVER OF THEIR RESPECTIVE PASS-BAND CHARACTERISTICS AND TO PRODUCE OUTPUT SIGNALS OF UNEQUAL AMPLITUDES IN RESPONSE TO AN APPLIED SIGNAL HAVING A FREQUENCY FALLING IN THE REGION OF OVERLAP OF THEIR RESPECTIVE PASS-BAND CHARACTERISTICS AND TO EITHER SIDE OF THE POINT OF CROSS-OVER, MEANS FOR APPLYING AN INPUT SIGNAL IN PARALLEL TO THE INPUT TERMINALS OF ALL OF SAID FILTERS, AND A THRESHOLD RATIO DETECTOR HAVING A LIKE PLURALITY OF INPUT TERMINALS CONNECTED TO RESPECTIVE FILTER OUTPUT TERMINALS AND A LIKE PLURALITY OF OUTPUT TERMINALS, SAID THRESHOLD RATIO DETECTOR INCLUDING MEANS OPERATIVE TO ESTABLISH A THRESHOLD LEVEL PROPORTIONAL TO THE RATIO OF THE AMPLITUDES OF THE LARGER TO THE SMALLER OUTPUT SIGNALS PRODUCED BY ANY TWO ADJACENT FILTERS IN RESPONSE TO FIRST AND SECOND INPUT SIGNALS HAVING FIRST AND SECOND FREQUENCIES RESPECTIVELY BELOW AND ABOVE THE FREQUENCY AT THE POINT OF CROSS-OVER OF THE PASS-BAND CHARACTERISTICS OF SAID TWO ADJACENT FILTERS, SAID FIRST AND SECOND FREQUENCIES DETERMINING THE LOWER AND UPPER BOUNDARIES, RESPECTIVELY, OF A SECOND PLURALITY OF ARBITRARILY SELECTED CHANNELS EACH NARROWER THAN THE AFORESAID ADJACENT CHANNELS AND RESPECTIVELY STRADDLING THE POINTS OF CROSS-OVER OF THE PASSBAND CHARACTERISTICS OF SUCCESSIVE ADJACENT FILTERS, SAID THRESHOLD RATIO DETECTOR BEING OPERATIVE TO PRODUCE A SIGNAL AT ONE OR THE OTHER OF THE OUTPUT TERMINALS OF SAID DETECTOR CORRESPONDING TO ANY TWO ADJACENT FILTERS WHEN THE RATIO OF THE LARGER TO THE SMALLER OUTPUT SIGNALS FROM SAID ANY TWO ADJACENT FILTERS IN RESPONSE TO A GIVEN INPUT SIGNAL EXCEEDS THE RATIO DETERMINED BY SAID THRESHOLD LEVEL, INDICATIVE THAT THE FREQUENCY OF THE GIVEN INPUT SIGNAL IS OUTSIDE THE ARBITRARILY SELECTED CHANNEL STRADDLING THE POINT OF CROSS-OVER OF THE BAND-PASS CHARACTERISTICS OF SAID ANY TWO ADJACENT FILTERS, AND TO PRODUCE A SIGNAL AT THE OUTPUT TERMINALS OF SAID DETECTOR CORRESPONDING TO BOTH OF SAID ANY TWO ADJACENT FILTERS WHEN THE RATIO OF THE LARGER TO THE SMALLER OUTPUT SIGNALS FROM SAID ANY TWO ADJACENT FILTERS IN RESPONSE TO SAID GIVEN INPUT SIGNAL IS LESS THAN THE RATIO DETERMINED BY SAID THRESHOLD LEVEL, INDICATIVE THAT THE FREQUENCY OF SAID GIVEN INPUT SIGNAL IS WITHIN THE ARBITRARILY SELECTED CHANNEL STRADDLING THE POINT OF CROSS-OVER OF THE PASS-BAND CHARACTERISTICS OF SAID ANY TWO ADJACENT FILTERS.

Claim 2

A SYSTEM FOR CHANNELIZING ACCORDING TO FREQUENCY SIGNALS WHICH MAY HAVE ANY FREQUENCY WITHIN A PREDETERMINED BAND OF INTEREST COMPRISING, IN COMBINATION, A PLURALITY OF BAND PASS FILTERS EACH HAVING INPUT AND OUTPUT TERMINALS AND RESPECTIVELY RESPONSIVE TO FREQUENCIES IN SUCCESSIVE ADJACENT SUB-BANDS OF SAID BAND OF INTEREST AND HAVING SIMILAR PASS-BAND CHARACTERISTICS, THE PASSBAND CHARACTERISTIC OF EACH OF SAID FILTERS CROSSING OVER THE CHARACTERISTICS OF THE TWO FILTERS ADJACENT THERETO TO THEREBY DEFINE A PLURALITY OF ADJACENT CHANNELS OF A WIDTH DETERMINED BY THE SPACING BETWEEN THE POINTS OF CROSS-OVER OF ADJACENT PASS-BAND CHARACTERISTICS, ANY TWO ADJACENT FILTERS BEING OPERATIVE TO PRODUCE OUTPUT SIGNALS OF EQUAL AMPLITUDES IN RESPONSE TO AN APPLIED SIGNAL HAVING A FREQUENCY FALLING AT THE POINT OF CROSS-OVER OF THEIR RESPECTIVE PASS-BAND CHARACTERISTICS AND TO PRODUCE OUTPUT SIGNALS OF UNEQUAL AMPLITUDES IN RESPONSE TO AN APPLIED SIGNAL HAVING A FREQUENCY FALLING IN THE REGION OF OVERLAP OF THEIR RESPECTIVE PASS-BAND CHARACTERISTICS AND TO EITHER SIDE OF THE POINT OF CROSS-OVER, MEANS FOR APPLYING AN INPUT SIGNAL IN PARALLEL TO THE INPUT TERMINALS OF ALL OF SAID FILTERS, AND A THRESHOLD RATIO DETECTOR HAVING A LIKE PLURALITY OF INPUT TERMINALS CONNECTED TO RESPECTIVE FILTER OUTPUT TERMINALS AND A LIKE PLURALITY OF OUTPUT TERMINALS, SAID THRESHOLD RATIO DETECTOR INCLUDING MEANS OPERATIVE TO ESTABLISH A THRESHOLD LEVEL PROPORTIONAL TO THE RATIO OF THE AMPLITUDES OF THE LARGER TO THE SMALLER OUTPUT SIGNALS PRODUCED BY ANY TWO ADJACENT FILTERS IN RESPONSE TO FIRST AND SECOND INPUT SIGNALS HAVING FIRST AND SECOND FREQUENCIES RESPECTIVELY BELOW AND ABOVE THE FREQUENCY AT THE POINT OF CROSS-OVER OF THE PASS-BAND CHARACTERISTICS OF SAID TWO ADJACENT FILTERS, SAID FIRST AND SECOND FREQUENCIES DETERMINING THE LOWER AND UPPER BOUNDARIES, RESPECTIVELY, OF A SECOND PLURALITY OF ARBITRARILY SELECTED CHANNELS EACH NARROWER THAN THE AFORESAID ADJACENT CHANNELS AND RESPECTIVELY STRADDLING THE POINTS OF CROSS-OVER OF THE PASSBAND CHARACTERISTICS OF SUCCESSIVE ADJACENT FILTERS, SAID THRESHOLD RATIO DETECTOR BEING OPERATIVE TO PRODUCE A SIGNAL AT ONE OR THE OTHER OF THE OUTPUT TERMINALS OF SAID DETECTOR CORRESPONDING TO ANY TWO ADJACENT FILTERS WHEN THE RATIO OF THE LARGER TO THE SMALLER OUTPUT SIGNALS FROM SAID ANY TWO ADJACENT FILTERS IN RESPONSE TO A GIVEN INPUT SIGNAL EXCEEDS THE RATIO DETERMINED BY SAID THRESHOLD LEVEL, INDICATIVE THAT THE FREQUENCY OF THE GIVEN INPUT SIGNAL IS OUTSIDE THE ARBITRARILY SELECTED CHANNEL STRADDLING THE POINT OF CROSS-OVER OF THE BAND-PASS CHARACTERISTICS OF SAID ANY TWO ADJACENT FILTERS, AND TO PRODUCE A SIGNAL AT THE OUTPUT TERMINALS OF SAID DETECTOR CORRESPONDING TO BOTH OF SAID ANY TWO ADJACENT FILTERS WHEN THE RATIO OF THE LARGER TO THE SMALLER OUTPUT SIGNALS FROM SAID ANY TWO ADJACENT FILTERS IN RESPONSE TO SAID GIVEN INPUT SIGNAL IS LESS THAN THE RATIO DETERMINED BY SAID THRESHOLD LEVEL, INDICATIVE THAT THE FREQUENCY OF SAID GIVEN INPUT SIGNAL IS WITHIN THE ARBITRARILY SELECTED CHANNEL STRADDLING THE POINT OF CROSS-OVER OF THE PASS-BAND CHARACTERISTICS OF SAID ANY TWO ADJACENT FILTERS.
