摘 要

    本設(shè)計(jì)主要講了運(yùn)用模擬技術(shù)和數(shù)字技術(shù)設(shè)計(jì)數(shù)字顯示多路電壓的一些原理工作的方法，以及在設(shè)計(jì)中應(yīng)該注意的一些事情，而且在設(shè)計(jì)中也詳細(xì)的介紹了所用芯片的功能及一些使用方法，因?yàn)槲覀兯�設(shè)計(jì)電路圖時(shí)用到了Protel 2004因此在本設(shè)計(jì)中也介紹了一點(diǎn)Protel 2004的知識(shí)。雖然對(duì)于本書設(shè)計(jì)中我們介紹的芯片知識(shí)和Protel 2004的知識(shí)可能較多，由有經(jīng)驗(yàn)的設(shè)計(jì)者來看，這根本是不適用，是沒有必要做的事。但我想如果面向的是那些初學(xué)者以及一些業(yè)余愛好者就不一樣了，本設(shè)計(jì)中的知識(shí)不僅能讓他們知道數(shù)字顯示的制作過程，注意要?jiǎng)t，而且我們所介紹的基礎(chǔ)知識(shí)也能擴(kuò)展出他們的思維讓他們?cè)谝院蟮脑O(shè)計(jì)中舉一反三，對(duì)于他們以后的設(shè)計(jì)生涯有著很好的幫助。本設(shè)計(jì)中的特點(diǎn)是簡單、易懂、入門塊，是初學(xué)者不錯(cuò)的選擇。當(dāng)然本設(shè)計(jì)中也有很多不足，設(shè)計(jì)中不能體現(xiàn)出專業(yè)人的一面，希望多多提出意見，我們及時(shí)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
