Calculation of travelling waves on transmission systems by finite differencess

The paper is concerned with attenuation and distortion of travelling waves on transmission systems. The conventional calculation of such phenomena is based on matrix operational methods: a different approach is suggested, namely the method of finite differences, which as an iterative numerical method is ideally suited to consideration of nonlinearities. A central-difference formula is employed to illustrate the behaviour of standard waves on model systems, subject to stability criteria. The authors set out mainly to investigate the general procedure of such a method, and expect that the work will be further extended to be of practical use in the study of travelling waves.
