Abstract :
An RDS network contains positive resistors, ideal diodes, independent voltage sources, and independent current sources. This paper presents conditions which are necessary and sufficient for a driving-point characteristic and a transfer characteristic to be realizable by an RDS two-port terminated in a twoterminal RDS load. The sufficient conditions are established by showing how the desired two-port is constructed. The resulting network is a physically symmetric lattice. Additional necessary and sufficient conditions are found for the two-port to be grounded, and a procedure for realizing characteristics which satisfy these additional conditions is presented. Other network configurations which realize RDS driving-point and transfer functions are then considered. A simple method for determining the number of elements in the various configurations is developed. This number depends on the number and location of the breakpoints in the driving-point, transfer, and load characteristics, and can be determined without synthesizing the network.
