摘要
在当代许多电子信息系统中,信号源的性能参数往往对系统的功能起着决定性作用。采用直接数字频率合成技术(Direct Digital Synthesize,DDS),基于现场可编程门阵列(Field-Programmable Gate Array,FPGA)设计了能同时输出4路信号的高精度信号发生器。同时依靠串口通信的方式,通过PC端的控制界面实时调节系统输出信号的频率、相位和死区时间。
In many contemporary electronic information systems,the performance parameters of a signal source often play a decisive role in the function of the system.In this paper,using Direct Digital Synthesize(DDS),a high-precision signal generator capable of simultaneously outputting four waves is designed based on Field-Programmable Gate Array(FPGA).At the same time,relying on the serial communication mode,the frequency,phase and dead time of the system output signal are adjusted in real time through the control interface of the PC.
