Claim 1
Independent Claim
146 words
IN COMBINATION WITH A SOURCE OF INPUT SIGNALS HAVING AN ALTERNATING CURRENT COMPONENT AND A CONTROLLABLE DIRECT CURRENT COMPONENT WITH RESPECT TO GROUND, A PLURALITY OF DIFFERENTIAL AMPLIFIERS, EACH HAVING A PAIR OF INPUT TERMINALS AND A PAIR OF OUTPUT TERMINALS, SAID INPUT TERMINALS BEING CONNECTED IN SERIES WITH RESPECT TO GROUND; A SOURCE OF BIAS VOLTAGE CONNECTED BETWEEN EACH OF SAID PAIRS OF INPUT TERMINALS; AND A PLURALITY OF DIODES, THE TERMINAL OF ONE POLARITY OF EACH OF SAID DIODES BEING CONNECTED TO A CORRESPONDING ONE OF SAID INPUT TERMINALS, THE TERMINALS OF THE OTHER POLARITY OF ALL OF SAID DIODES BEING CONNECTED TOGETHER AND TO SAID SOURCE OF INPUT SIGNALS, WHEREBY THE DIFFERENTIAL AMPLIFIER WHOSE SOURCE OF BIAS VOLTAGE INCLUDES THE LEVEL OF SAID DIRECT CURRENT COMPONENT HAS A DIFFERENTIAL ALTERNATING CURRENT COMPONENT APPLIED ACROSS ITS PAIR OF INPUT TERMINALS AND A CORRESPONDING OUTPUT.
