1北京理工大学珠海学院 2020 届本科生毕业设计基于 LabVIEW 的虚拟仪器平台设计-多功能函数信号发生器基于 LabVIEW 的虚拟仪器平台设计-多功能函数信号发生器摘要函数信号发生器（Function Signal Generator)是一种信号发生装置，能产生某些特定的周期性时间函数波形(正弦波、方波、三角波、锯齿波等)信号，频率范围可从少则几微赫兹到几十兆赫兹，它在实验和研究中得到了广泛的应用。本课题的任务是自行研究设计出一种基于 labview 的虚拟仪器平台的函数信号发生器。主要思路是用LabVIEW 设计好程序框图里的信号发生器模块，通过程序框图加上频率、周期、占空比等控件，设计出一个简单美观、功能齐全的前面板，通过示波器观察最后得到的波形。关键词：信号发生器；虚拟仪器实验平台；产生信号2北京理工大学珠海学院 2020 届本科生毕业设计Design of Virtual Instrument Platform Based on LabVIEW - Multifunctional Function Signal GeneratorAbstractFunction Signal Generator is a kind of Signal Generator, which can generate some specific periodic time Function waveform (sine waveform, square waveform, triangular waveform, sawtooth waveform, etc.) Signal.the frequency range can be from a few micro-hertz to tens of megahertz.It has been widely used in experiments and research.The task of this project is to design a Function Signal Generator based on labVIEW virtual instrument platform.The main idea is to use LabVIEW to design the signal generator module in the program block diagram, through the program block diagram plus frequency, period, duty cycle and other controls, design a simple and beautiful, fully functional front panel, through oscilloscope observation of the final waveform.Keyword:Signal generator;The Virtual Instrument experiment platform;Signal generation3北京理工大学珠海学院 2020 届本科生毕业设计目录1 绪论.........................................................................................................................................................61.1 选题背景...........
