| Summary: | 碩士 === 中華大學 === 電機工程研究所 === 86 === The purpose of the paper is mainly focused on the necessary elementary theories while studying Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC). I collected all the theories and tried to combine tern. I also tried to find out a simple model whice could simulate the radiation interference of electronic field on the current transmission line. The model can be used as designers reference when they are designing transmission line.
For reaching the above purpose, I chose the general Printed Circuit Board (PCB) sold on the market as the hardware. There are many simple transmission lines on the PCB, so I can get the necessary experiment figures by testing the figures of EMI/EMC.
I have taken the advantage of the existed mathematics calculation software. The result of calculation is compared with the result of the experiment to simulate the possible results in reality. In addition, for observing how the factors on to transmission lenes affect the radiation strength of electronic field produced by the circuit I make a little change on the factors which could affect the transmission lines on PCB. Finally, I have made my effort on analyzing the procedure of circut design and gotten some key points should be paid attention during the procedure.
