摘　　要：基于FPAG技术,对采样获得的ROM数据,通过功能模块对其进行选择乘法处理,并经DAC芯片加以转换。实现了信号的产生与调制(2ASK,2PSK,2FSK)。经过系统仿真、SignalTapⅡ分析以及在示波器上的观察显示,信号稳定可靠,高频谐波少。整个系统结构紧凑,实现灵活方便,可扩展性强。Based on the FPGA technology, the signals were generated and modulated （2ASK, 2PSK, 2FSK） by multiplying the ROM data through function modules and trensforming them with DAC chips. The system simulation, SignalTap Ⅱ analysis and oscilloscope displays showed the steady and reliable, less high-frequency harmonics signals. The system implementation featured flexibility, and a compact design with good extensibility.
