Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
123 words
A DETECTOR CIRCUIT FOR DEVELOPING AN OUTPUT SIGNAL COMPRISING A SOURCE OF INPUT SIGNALS OF VARYING AMPLITUDE, A BI-DIRECTIONAL SWITCH HAVING ONE END COUPLED TO SAID SOURCE, A STORAGE CAPACITOR COUPLED TO THE OTHER END OF SAID BI-DIRECTIONAL SWITCH TO MAINTAIN A VARIABLE STORED POTENTIAL, A FIRST CONSTANT CURRENT SOURCE COUPLED TO SAID BI-DIRECTIONAL SWITCH, A SECOND CONSTANT CURRENT SOURCE COUPLED TO SAID STORAGE CAPACITOR, FILTER MEANS COUPLED TO SAID STORAGE CAPACITOR WHEREBY SAID STORAGE CAPACITOR CHARGES FROM SAID FIRST CURRENT SOURCE AND DISCHARGES TO SAID SECOND CURRENT SOURCE AS DETERMINED BY A RATIO OF THE AMPLITUDE OF SAID STORED POTENTIAL AND THE INSTANTANEOUS AMPLITUDE OF SAID INPUT SIGNALS, SAID STORED POTENTIAL BEING APPLIED TO SAID FILTER MEANS TO DEVELOP THE OUTPUT SIGNAL.
