The coaxial cable is one of the most commonly used bandwidth limited signal transmission line.Dispersion is a signal distortion phenomenon which arises due to frequency dependence of phase velocity of signal components. This phenomenon was explained through time domain approach by studying time taken by signals of various frequencies to propagate through the cable, which eventually may cause signals to combine out of phase leading to distortion. This study concludes that dispersion effects become significant at higher frequency ranges in electromagnetic spectrum , and places a limit on bandwidth of signal to ensure distortion free transmission. It has implications in field of RF and microwave transmission, as well as computer and instrumentation data connections, dealing with high frequency signals.
