Synthesized network for signal transmission
Abstract
Abstract A SYNTHESIZED NETWORK IS FORMED EQUIVALENT TO A COAXIAL CABLE OF ANY DESIRED LENGTH USING DISTRIBUTED RC NETWORKS OF FINITE LENGTH CONSTRUCTED BY INTEGRATED CIRCUIT TECHNIQUES. A SYMMETRICAL NETWORK HAVING TWO INPUT AND TWO OUTPUT PORTS INCLUDES A FIRST PAIR OF UNIFORMLY DISTRIBUTED RC ELEMENTS IN SERIES BRANCHES OF THE SYMMETRICAL CIRCUIT AND A SECOND PAIR OF UNIFORMLY DISTRIBUTED RC ELEMENTS IN PARALLEL BRANCHES. THE FIRST AND SECOND PAIRS OF UNIFORMLY DISTRIBUTED ELEMENTS ARE OF SUBSTANTIALLY IDENTICAL LENGTH WITH EACH OF THE FIRST PAIR HAVING A PAIR OF TERMINALS SHORT CIRCUITED AND EACH OF THE SECOND PAIR HAVING A PAIR OF TERMINALS OPEN CIRCUITED. A THIRD UNIFORMLY DISTRIBUTED RC ELEMENT IS CONNECTED TO THE OUTPUT TERMINALS OF SAID SYMMETRICAL CIRCUIT AND HAS A DRIVING POINT IMPEDANCE SUBSTANTIALLY EQUAL TO THE IMAGE IMPEDANCE OF SAID SYMMETRICAL NETWORK. THE SYNTHESIZED NETWORK IS EQUIVALENT TO A COAXIAL CABLE OF LENGTH L AND HAVING A COAXIAL CABLE CONSTANT K WHERE THE TOTAL RESISTANCE RT AND CAPACITANCE CT OF EACH OF SAID FIRST AND SECOND UNIFORMLY DISTRIBUTED RC NETWORKS SATISFY THE CONDITION D R A W I N G
