智能函数信号发生器的设计

The Design of Intelligent Function Signal Generator

函数信号发生器是一种常用的信号源,它广泛地应用在电子技术实验、自动控制系统和其他科研领域[5]。目前用集成电路组成的函数信号发生器,大都需手动进行波形切换,一般可靠性较差,准确度较低,难以满足科研和高精度实验的需要。对设计正弦波、方波和三角波三种波形进行了研究,利用VHDL语言[1]进行源程序代码编写,在QuartusII平台下进行编译[1,4]并通过仿真工具ModelSim进行测试,最后用EPF10K10LC84-4芯片实现其功能。

Function signal generator is a kind of general signal source, it applies extensively in the function signal generator of electronic technical experiment, automatic control system and other research fields. Now signal general formed with integrated circuit needs to carry out waveform switch by hand mostly, it has lower accuracy and reliabilitY comparatively, it is hard to satisfy research with the needs of the experiment of high accuracy. This article indicates how to design the intelligent function generator to produce sine wave, triangular wave and square wave, it was programmed by VHDL, compiled by Quartus Ⅱ and simulated by ModelSim. Last, it was realized its function by the chip of EPF10K10LC84 - 4.
