摘要
本文基于FPGA设计了一个正弦信号发生器,采用直接数字频率合成(DDS)技术,实现了信号发生器的频率、相位可以控制。并对系统进行了Modelsin功能仿真,仿真结果证实此次设计有较好的可靠性,且产生的波形最高频率可以达到1.25M,频率稳定度在1%以内。
This paper describes the design of a sinusoidal signal generator based on FPGA, with direct digital fl＇equency synthesis （DDS） technology, the frequency, the phase signal generator can control. And the system of the Modelsin function simulation, simulation results show that this design has good reliability, high frequency and waveform generation can reach 1.25M, frequency stability within 1%.
