Claims

1. A TRAVELING-WAVE SIGNAL TRANSLATING SYSTEM COMPRISING IN COMBINATION, A SIGNAL TRANSMISSION-LINE STRUCTURE INCLUDING A PAIR OF TRANSMISSION-LINE CONDUCTOR ELEMENTS, MEANS FOR APPLYING AN INPUT SIGNAL TO ONE END OF SAID STRUCTURE IN CONNECTION WITH THE INPUT ENDS OF SAID CONDUCTOR ELEMENTS, MEANS FOR DERIVING AN OUTPUT SIGNAL FROM THE OPPOSITE END OF SAID LINE STRUCTURE IN CONNECTION WITH THE OUTPUT ENDS OF SAID CONDUCTOR ELEMENTS, A SEMI-CONDUCTOR ELEMENT EXTENDING ALONG AND BETWEEN THE CONDUCTOR ELEMENTS OF THE TRANSMISSION LINE STRUCTURE, MEANS FOR ESTABLISHING A TRANSVERSE MAGNETIC BIAS FIELD THROUGH THE SEMICONDUCTOR ELEMENT AND ADDITIONAL MEANS FOR APPLYING CONTROL CURRENTS LONGITUDINALLY THROUGH SAID SEMICONDUCTOR ELEMENT AND TRANSVERSELY THEREOF BETWEEN THE CONDUCTORS, THE DIRECTION OF SAID LONGITUDINAL CURRENT BEING SUCH THAT A CHANGE IN MAGNETIC FIELD THROUGH SAID SEMICONDUCTOR ELEMENT TENDS TO PRODUCE A CHANGE IN THE TRANSVERSE CURRENT DUE TO HALL-EFFECT IN A DIRECTION TENDING TO MAINTAIN THE TRANSVERSE CONTROL CURRENT CONSTANT AS THE MAGNETO-RESISTANCE OF SAID SEMICONDUCTOR ELEMENT CHANGES DUE TO SAID CHANGE IN MAGNETIC FIELD, TO THEREBY INCREASE THE EFFECTIVE IMPEDANCE BETWEEN SAID CONDUCTOR ELEMENTS.
