Simulating and Controlling the Effects of Transmission Line Impedance Mismatches

Convenient equations for simulating the effects of transmission line impedance mismatches are derived from basic theory. These equations prove useful in controlling the transient response of a transmission line. The simulation equation for the load voltage is used to create design equations. Acceptable impedance mismatches are demonstrated in the context of criteria for acceptable transient voltages on a high-speed interconnection. The process of dividing the noise margin between crosstalk and reflections will be examined. A definition of high speed signals is presented.
