Claim 1
Independent Claim
147 words
A SYSTEM FOR DETERMINING THE PRESENCE OF CERTAIN FREQUENCIES IN AN INPUT SIGNAL COMPRISING MEANS FOR GENERATING A LIGHT LINE VARIABLE IN INTENSITY ACCORDING TO SAID INPUT SIGNAL, A LINE OF LIGHT-INTEGRATING AREAS EXPOSED TO SAID LIGHT LINE, LIGHT-MODULATING MEANS INTERPOSED BETWEEN SAID LIGHT LINE AND SAID LIGHT-INTEGRATING AREAS, SAID LIGHTMODULATING MEANS BEING ADPAPTED TO MODULATE EACH OF A PLURALITY OF TRANSVERSELY-SPACED SEGMENTS OF SAID LIGHT LINE, EACH OF SAID SEGMENTS BEING MODULATED AT ONE OF SAID CERTAIN FREQUENCIES AND A PLURALITY OF DIFFERENT PHASE RELATIONSHIPS, MEANS FOR SEQUENTIALLY SAMPLING EACH OF SAID LIGHT-INTEGRATING AREAS AND DERIVING OUTPUT SIGNALS THEREFROM, PROCESSING MEANS CONNECTED TO SAID SAMPLING MEANS TO RECEIVE SAID OUTPUT SIGNALS AND ADAPTED TO PRODUCE A COMPOSITE OUTPUT FOR EACH OF SAID SEGMENTS, SAID COMPOSITE SIGNAL HAVING AN AMPLITUDE INDEPENDENT OF THE PHASE OF SAID INPUT SIGNAL, AND MEANS FOR DISPLAYING SAID COMPOSITE SIGNALS IN SEQUENCE.
