摘　　要：本设计利用EDA开发平台,采用可编程逻辑器件CPLD,利用FDDS技术,以VHDL语言为设计基础,使信号发生器的硬件功能可通过编程来实现0~5V的正弦波、三角波、方波和锯齿波信号.从而大大地节省了硬件开销和软件的编程难度,进而实现了一种性能较高的信号发生器.与模拟信号发生器相比,该系统具有波形稳定、精确度高、抗干扰性能力强、轻便、现场可编程、使用方便等特点.This design uses the EDA development platform, programmable logic device CPLD, FDDS technology, and VHDL language as the basis, so that the hardware function of signal generator can be programed to realize to achieve 0-5V sine wave, triangle wave, square wave and serrated wave signals. Thereby, the hardware cost and software programming difficulty are greatly decreased, and then a signal generator with high performance is realized. Compared with analog signal generator, the system has the characteristics of stable wave form, high accuracy, strong anti-jamming ability, portability, field programmability and being easy to use.
