正弦波﹑方波﹑三角波的发生电路设计摘要现今世界中电子技术与电子产品的应用越加广泛，人们对电子技术的要求也越来越高。因此如何根据实际要求设计出简便有用的电子技术物品便显得尤为重要。灵活、快速的选用不同特征的信号源成了现代测量技术值得深化讨论的课题。能将简单的易猎取的信号转换为自己所需的复杂信号是一项必不可少的技术。我们有必要做好这相关方面的讨论，为被测电路提供所需要的信号与各种波形，以便完成各种相关试验。信号源在各种试验应用和实验测试处理中，仿真各种测试信号，提供给被测电路，用来满足实验的各种要求。关键词：单片机，信号发生器，波形ABSTRACT ： The application of electronic technology and electronic products in today's world increasingly extensive, people also more and more high to the requirement of electronic technology. According to actual requirements so how to design simple and practical electronic technology items, it becomes very important. Flexible, fast, choose different characteristics of the signal source is worth studying deeply the modern measuring technology. Can be simple, easy to obtain signal can be converted into their complex signal is an essential technology. It is necessary for us to do the related research, to provide the required signal circuit under test and various waveform, to complete various related experiment. Signal source in various test application and test processing, simulation of testing signal, provided to the circuit under test, to satisfy the requirements of the experiments.KEY WORDS:Microcontroller, signal generator, waveform目录第一章前言 41.1 课题讨论背景 41.2 波形介绍 51.2.1 正弦波 51.2.2 三角波 51.2.3 方波 61.3 硬件介绍 61.3.1 AT89C51 单片机 61.3.2 DAC0832 转换器 7第二章发生电路设计原理 92.1 功能和基本原理 92.2 红外电路 92.3 复位电路 102.4LCD 显示部分电路 102.5 电源部分 112.6 外部时钟电路 112.7 显示接口电路 112.8 独立按键部分 122.9 波形转换电路 122.10 串...
