摘要
针对FPGA芯片和高速DA芯片,实现了双通道信号发生器,提出了直接数字式合成各种波形技术的设计思路,具体硬件电路及编程实现方法,通过在FPGA中建立一个NOIS ii软核用C语言编程实现对信号输出的控制。用户可通过按键控制FPGA输出想要的波形,还可以根据需要自行输入想要的频率,由于此系统的体积小,信号失真小,在工程应用上具有实际意义。
For the dual-channel signal generator based on FPGA and the high speed DA,we proposed the technical design ideas of Direct Digital Synthesizer（DDS）.Describe the hardware circuits and programming methods, through the FPGA to create a NOIS ii core which can be written in C programming language to achieve the control of the signal output.Users can control the output waveform of the FPGA through the key ,can also manually enter the desired frequency by they need. This system is small and the signal output is without distortion,it have practical significance in engineering applications.
