摘 要

    本设计主要讲了运用模拟技术和数字技术设计数字显示多路电压的一些原理工作的方法，以及在设计中应该注意的一些事情，而且在设计中也详细的介绍了所用芯片的功能及一些使用方法，因为我们所设计电路图时用到了Protel 2004因此在本设计中也介绍了一点Protel 2004的知识。虽然对于本书设计中我们介绍的芯片知识和Protel 2004的知识可能较多，由有经验的设计者来看，这根本是不适用，是没有必要做的事。但我想如果面向的是那些初学者以及一些业余爱好者就不一样了，本设计中的知识不仅能让他们知道数字显示的制作过程，注意要则，而且我们所介绍的基础知识也能扩展出他们的思维让他们在以后的设计中举一反三，对于他们以后的设计生涯有着很好的帮助。本设计中的特点是简单、易懂、入门块，是初学者不错的选择。当然本设计中也有很多不足，设计中不能体现出专业人的一面，希望多多提出意见，我们及时改正。

Abstract
This design mainly spoke the utilization simulation technology and the numeral technical design numeral demonstration multi-channel voltage some principle work method, as well as some matters which should pay attention in the design, moreover the detailed introduction has also used the chip in the design the function and some application method, because we design time the circuit diagram used Protel 2004 therefore also introduced Protel 2004 knowledge in this design. Although we introduced regarding this book design in the chip knowledge and the Protel 2004 knowledge are possibly many, looked by the experienced designer, this is not suitable, is not the matter which unnecessary does. But I thought if faces is these beginners as well as some amateurs is dissimilar, not only in this design knowledge can let them know the digital demonstration the manufacture process, the attention important regulation, moreover we introduced the elementary knowledge also can expand their thought to let them extrapolate in later design, has the very good help regarding they later design profession. In this design characteristic is simple, easy to understand, the basic block, is the beginner good choice. Certainly in this design also has very many insufficiencies, in the design cannot manifest specialized person''s one side, hoped very much gives the comment, we correct promptly.

Key words: Digital demonstration multi-channel voltages, simulation technology, digital technology, Protel 2004
