武汉理工大学《protel课程设计》

摘要

Protel设计系统是世界上第一套将EDA环境引入到Windows环境中的EDA开发工具，是具有强大功能的电子设计CDA软件，它具有原理图设计、印刷电路板（PCB）、报表制作、电路仿真以及逻辑器件设计等功能，是进行电子设计最有用的软件之一。

信号发生器又称为信号源或振荡器，各种波形曲线均可以用三角函数来表示。能够产生多种波形，如三角波、锯齿波、矩形波（含方波）、正弦波的电路被称为函数信号发生器。它在电路实验和设备检测中具有十分广泛的用途。

本次Protel课程设计实现函数信号发生器的原理图绘制，PCB板制作以及电路仿真。用运放构成的比较器和积分器实现方波和三角波的输出，再经差分放大产生正余弦波形。

关键词：Protel,函数发生器，仿真

Abstrat

Protel design system is the world’s first set of EDA developing tools which introduces EDA environment to Windows environment.It is a electronic design CDA software with strong functions,it has a schematic design,printed circuit board(PCB),circuit emulation and logic device design and so on.It’s one of the most useful software in circuit design.

Signal generator is also called signal generator or oscillator.All kinds of wave form can be expressed in trigonometric function.The circuit which can generate some waves ,such as triangular wave, wawtooth wave,rectangle wave(including square wave),sine wave is called Function signal generator.It is used widely in circuit experiment and testing equipment.

This Protel curriculum design is wanted to draw the schematic diagram,make the PCB,and circuit simulating.It use the compataor and …… 此处隐藏：4817字，全部文档内容请下载后查看。喜欢就下载吧 ……
