本文介绍了一个全自动图形设计软件——HDSMITH,该软件以准确,高效,不必人工转图、读图及计算,使用方便的极大优势取代传统的SMITH圆图加计算器,而在自动计算、设计方面则比传统的的方法更胜一筹。该软件以SMITH圆图为基础,凡是在圆图上可做的工作均可由该软件自动完成,并可进行阻抗匹配和变换,低噪声或高增益放大器设计,稳定圆,等增益圆,等噪声圆等图形的自动绘制.而且具有各种计算功能;软件具有良好的用户界面,各项功能均可通过选择菜单实现,设计采用人机交互,使用简便,功能齐全,既可作为高频、微波及天线工程设计人员日常必备工具,又十分适于学校教学使用。
This paper introduces a fully automatic graphics design software - HDSMITH, the software accurately and efficiently, without manual drawing, reading and calculation, the great advantage of easy to use to replace the traditional SMITH circular graph plus calculator, automatic calculation , The design is superior to the traditional method. The software is based on the SMITH chart, any work done on the chart can be done automatically by the software, and can be impedance matching and transformation, low noise or high gain amplifier design, such as stable circles, such as the gain of the circle, such as noise Circle and other graphics automatic drawing. And has a variety of computing functions; software has a good user interface, the various functions can be achieved through the choice of menu design using human-computer interaction, easy to use, fully functional, both as a high-frequency, microwave And antenna engineering designers daily essential tools, but also very suitable for school teaching.
