在印刷电路板上的高频信号中，波形失真是一个严重的问题。为了克服这一问题，我们已经提出了分段传输线(STL)方法，它将传输线划分为几个不同线宽的段。调整每条线宽，使反射噪声相互抵消，使信号失真最小。在本研究中，我们首先分析了STL的波形整形机制。接下来，我们将STL应用于高速计算机的双列直插式内存模块(DIMM)时钟线。这些结果为STL的设计提供了有益的指导，显示了STL的有效性。
Waveform distortion is a serious problem in higher-frequency signals on printed circuit boards (PCBs). To overcome this problem, we have already proposed the segmental transmission line (STL) method, which divides transmission lines into several segments with different line widths. Each line width is adjusted to make the reflection noises cancel each other out in order to minimize the signal distortion. In this research, we first analyze the waveform reshaping mechanism of STL. Next, we apply STL to a dual in-line memory module (DIMM) clock-line for high-speed computers. The results give helpful guidelines for STL designs, which shows the efficiency of STL.
