摘　　要：作为调试设备,数字信号发生器是数字信号处理中不可缺少的一部分,广泛的应用在生产生活当中。由于FPGA集密度高,功耗低,体积小以及可靠性高等优点于一身,所以采用Altera公司生产的FPGA实现数字信号发生器的设计,该数字信号发生器能够产生可调频率的正弦波、方波、三角波和锯齿波。通过硬件系统测试,结果表明:系统精度较高、带负载能力较强、运行稳定。As debugging equipment,the digital signal generator was an indispensable part in digital signal processing,and was used in production and life.Since FPGA advantage of high density,low power consumption,small volume and high reliability,FPGA of Altera company was used to realize the design of digital signal generator,and the digital signal generator could generate sine wave, square wave,triangle wave and sawtooth wave of adjustable frequency.Through the hardware test,the results showed that the system had the characteristics of higher accuracy,strong load capacity,stable operation.
