Selectively shunted series-switching transmission gates

Claim 1

A SWITCHING SYSTEM FOR CONNECTING A PLURALITY OF DISCRETE INPUT SIGNALS TO A COMMON OUTPUT LOAD COMPRISING, A PLURALITY OF DISCRETE INPUT SIGNAL SOURCES, A COMMON OUTPUT LOAD, INDIVIDUAL SWITCHING CIRCUITS CONNECTED BETWEEN EACH SIGNAL SOURCE AND SAID COMMON OUTPUT LOAD FOR SELECTIVELY SWITCHING SAID INPUT SIGNALS TO SAID OUTPUT LOAD EACH OF SAID SWITCHING CIRCUITS INCLUDING ELECTRONIC VALVE, MEANS HAVING AN INPUT CONNECTED TO ONE OF SAID SIGNAL SOURECES AND AN OUTPUT CONNECTED TO SAID COMMON LOAD SAID VALVE MEANS BEING RENDERED CONDUCTIVE BY BIAS OF ONE POLARITY AT ITS INPUT BUT NON-CONDUCTIVE BY BIAS OF ONE POSITE POLARITY THEREAT, ASYMMETRIC IMPEDANCE MEANS EACH HAVING A LOW AND A HIGH IMPEDANCE STATE AND CONNECTED IN SHUNT WITH EACH OF SAID VALVE INPUTS IN SUCH A WAY THAT SAID MEANS EXHIBIT HIGH IMPORTANCE WHEN THE INPUT HAS SAID ONE POLARITY AND LOW IMPEDANCE WHEN SAID INPUT HAS SAID OPPOSITE POLARITY, COMMON BIASING MEANS CONNECTED TO THE INPUT OF EACH SWITCHING CIRCUIT AND HAVING SAID OPPOSITE POLARITY EFFECTIVE TO FORWARD BIAS EACH OF SAID ASYMMETRIC IMPEDANCES INTO A LOW IMPEDANCE STATE TO NORMALLY SUBSTANTIALLY SHORT CIECUIT THE INPUT OF EACH ELECTRONIC VALVE MEANS, AND DISCRETE SWITCHING MEANS FOR
