Apparatus for analyzing a signal having a plurality of peaks by normalization

Claim 1

APPARATUS FOR ANALYZING A SIGNAL HAVING A NUMBER OF PEAKS COMPRISING: INTEGRATION MEANS FOR INTEGRATING THE VARIOUS PEAKS OF THE SIGNAL, SAID SIGNAL BEING SUPPLIED TO SAID INTEGRATION MEANS, SAID INTEGRATION MEANS SUPPLYING A MECHANICAL OUTPUT PROPORTIONAL TO THE INTEGRATED VALUE; A FIRST SOURCE OF D.C. VOLTAGE; A PLURALITY OF POTENTIOMETERS, THERE BEING AT LEAST ONE POTENTIOMETER FOR EACH PEAK OF THE SIGNAL TO BE ANALYZED, SAID POTENTIOMETERS BEING CONNECTED IN A PARALLEL ARRANGEMENT TO SAID SOURCE OF D.C. VOLTAGE; A PLURALITY OF HIGH IMPEDANCES AND SWITCHES CONNECTED IN SERIES, EACH OF THE SLIDING CONTACTS OF SAID POTENTIOMETERS BEING CONNECTED TO ONE OF SAID HIGH IMPEDANCES AND SWITCHES, ALL OF SAID SWITCHES BEING CONNECTED TO A COMMON JUNCTION POINT; A SOURCE OF D.C. REFERENCE VOLTAGE, ONE SIDE OF SAID D.C. REFERENCE VOLTAGE BEING CONNECTED IN OPPOSITION TO SAID FIRST SOURCE OF D.C. VOLTAGE; A RESISTANCE, ONE SIDE OF SAID RESISTANCE BEING CONNECTED TO SAID COMMON JUNCTION POINT, THE OTHER SIDE OF SAID RESISTANCE BEING CONNECTED TO THE OTHER SIDE OF SAID D.C. REFERENCE VOLTAGE; A PROGRAMMING MEANS, SAID PROGRAMMING MEANS BEING COUPLED TO SAID INTEGRATING MEANS AND THE SLIDING CONTACTS OF SAID PLURALITY OF POTENTIOMETERS, SAID PROGRAMMING MEANS FOR EACH PEAK IN THE SIGNAL SEQUENTIALLY CONNECTING THE OUTPUT OF SAID INTEGRATING MEANS TO A DIFFERENT ONE OF SAID SLIDING CONTACTS TO MOVE ONE OF SAID SLIDING CONTACTS TO A POSITION ALONG THE POTENTIOMETER PROPORTIONAL TO THE INTEGRATED VALUE FOR EACH OF THE INDIVIDUAL PEAKS; SAID FIRST D.C. SOURCE BEING CONNECTED TO SAID POTENTIOMETERS; A SERVO MEANS, SAID SERVO MEANS BEING CONNECTED TO SAID FIRST D.C. SOURCE TO VARY SAID FIRST D.C. SOURCE, SAID SERVO MEANS BEING RESPONSIVE TO THE VOLTAGE ACROSS SAID RESISTOR TO VARY THE VOLTAGE OF SAID FIRST D.C. SOURCE UNTIL THE VOLTAGE ACROSS SAID RESISTOR EQUALS THE D.C. REFERENCE VOLTAGE; A RECORDING MEANS, A SECOND SWITCH MEANS, SAID PROGRAMMING MEANS BEING COUPLED TO SAID SECOND SWITCH MEANS AND THE SWITCH MEANS ASSOCIATED WITH THE HIGH IMPEDANCES OF THE INDIVIDUAL POTENTIONMETERS TO SEQUENTIALLY CONNECT SAID POTENTIOMETERS TO SAID RECORDING MEANS TO RECORD THE VOLTAGE ACROSS SAID POTENTIOMETERS.
