Driving-Point Function Synthesis Using Tapered RC Lines and Their Duals

Simple and composite lines have been defined for nonuniform transmission lines and their various configurations considered. The concept of duality has been extended to composite lines and their different configurations, and two theorems concerning these lines have been established. A procedure for realizing certain classes of irrational functions as driving-point functions has been presented using simple or composite lines and their duals. This includes the existing procedures for uniform and exponential lines.
