| Abstract: | The basic characters and the conditions in which signal line must be treated as transmission line are presented.The mathematic and physical impedance matching models of transmission line and the impedance computing formulas are also pointed out.As an example of transmission back-board in high speed emitter or receiver,not only the design process and parameter calculation of impedance matching in backboard transmission line are detailed,but aslo the influence to impedance from PCB craft are included according to the practice.It has important value for reference in analysis and design of impedance matching about transmission line. |
