Improvement of Pulse Shape by Reducing Ripple Using Coaxial Cable

Abstract

Even though pulse shape in rectangular form is desirable for most applications, pulse generated from coaxial cable has ripple and is not in desired rectangular shape. This study is to improve the pulse shape generated from coaxial cable to be rectangular shape. Coaxial cables with difference dielectric materials are studied for generation 100 ns pulse. The study has been carried out by state space representation method and MATLAB simulation for pulse forming network of Type-B which has same characteristics of coaxial cable. Ripple can be reduced to 2% to 3% increasing the inductance values next load higher than characteristics inductance of coaxial cable.
