摘要
现代测试领域中,经常需要信号发生器提供多种多样的的测试信号去检验实际电路中存在的设计问题。传统的信号发生器多采用模拟电路搭建。以正弦波信号发生器为例,结合DDS直接数字合成技术,基于FP-GA设计其他外围电路构成正弦波信号发生器。相比传统的模拟信号发生器,该电路具有设计简单,升级容易,波形稳定等特点。
In modern testing areas,signal generator often offers various test signals to find the actual problems existed in circuit design.But the traditional signal generator is designed by analog circuit.This paper introduces the sine wave signal generator based on FPGA and the technology of DDS,which has the characteristics of easy to upgrade,simple design and stable wave that compared with traditional analog signal generator.
