Claim 1
Independent Claim
112 words
IN A PATCHBOARD PROGRAMMED ANALOG COMPUTER, A SYSTEM FOR REDUCING CAPACITANCE BETWEEN A SUMMING JUNCTION AT THE PATCHABY AND A REMOTE OPERATIONAL AMPLIFIER CONNECTED TO THE SUMMING JUNCTION BY AN EXTENDED ELECTRICAL CONNECTING MEANS, COMPRISING: A HIGH-PRESS CIRCUIT CONNECTED IN SERIES WITH SAID EXTENDED ELECTRICAL CONNECTING MEANS AND CONNECTED DIRECTLY TO SAID SUMMING JUNCTION AT THE PATCHBAY, SAID CIRCUIT INCLUDING AN AMPLIFIER HAVING ITS INPUT TERMINAL CONNECTED TO SAID SUMMUNG JUNCTION AND ITS OUTPUT TERMINAL CONNECTED TO SAID EXTENDED ELECTRICAL CONNECTING MEANS, AND A LOW-PASS CIRCUIT CONNECTED IN PARALLEL WITH SAID HIGH-PASS CIRCUIT AND IN SERIES WITH SAID EXTENDED ELECTRICAL CONNECTING MEANS, AND CONNECTED DIRECTLY TO SAID SUMMING JUNCTION AT THE PATCHBAY.
