[SCM多功能高精度信号发生器的设计

Description: 摘要:直接数字频率合成(DDS)是七十年代初提出的一种新的频率合技术,其数字结构满足了现代电子系统的许多要求,因而得到了迅速地发展。现场可编程门阵列器件(FPGA)的出现,改变了现代电子数字系统的设计方法,提出了一种全新的设计模式。本设计结合这两项技术,并利用单片机控制灵活的特点,开发了一种新的函数波形发生器。在实现过程中,本设计选用了Altera公司的EP1C6Q240C8芯片作为产生波形数据的主芯片,充分利用了该芯片的超大集成性和快速性。在控制芯片上选用了AT89C51单片机作为控制芯片。本设计中,FPGA芯片的设计和与控制芯片的接口设计是一个难点,本文利用Altera的设计工具Quartus II并结合Verilog-HDL语言,采用硬件编程的方法很好地解决了这一问题。本文首先介绍了函数波形发生器的研究背景和DDS的理论。然后详尽地叙述了用EP1C6Q240C8完成DDS模块的设计过程,这是本设计的基础。接着分析了整个设计中应处理的问题,根据设计原理就功能上进行了划分,将整个仪器功能划分为控制模块、外围硬件、FPGA器件三个部分来实现。然后就这三个部分分别详细地进行了阐述。最后,通过系列实验,详细地说明了本设计的功能、性能、实现和实验结果。并结合在设计中的一些心得体会,提出了本设计中的一些不足和改进意见。通过实验说明,本设计达到了预定的要求,并证明了采用软硬件结合,利用DDS技术实现函数波形发生器的方法是可行的。 关键词:直接数字频率合成;现场可编程门阵列;函数波形发生器;频谱分析;仿真 含图原版论文
