The K-pulse and response waveforms for nonuniform transmission lines

Application of the K-pulse concept to a class of distributed-parameter systems which can be modeled by finite lengths of nonuniform transmission lies is demonstrated. The K-pulse of such a system is the excitation (input) waveform of finite duration which yields response waveforms of Finite duration at all points of the system. Numerical techniques using a finite element method are developed to derive accurate approximation of the K-pulse and response waveforms for uniform and nonuniform transmission lines. Comparison is made with exact results to illustrate the accuracy and utility of the method.
