| 摘 要： | 利用直接数字频率合成（Direct Digital Synthesis,DDS）技术,以现场可编程门阵列（Fieldprogrammable Gate Array,FPGA）芯片为载体,设计了一个信号发生器.该信号发生器能够产生频率、相位和幅度可调的周期信号.同时,DDS技术自身具有频率和相位调节功能,无需额外硬件调节电路.利用数模转换器基准电压可调特性设计实现了信号幅度调节.

| Abstract: | A new technology named Direct Digital Synthesis（ DDS） was applied on a FPGA chip to design a waveform generator. It can generate periodic waveform whose frequency,phase and amplitude were adjustable. Moreover,the waveform generator with DDS has the function of frequency and phase adjustment,so no additional circuit was needed. During the amplitude modulation design,the characteristics of reference voltage of the D /A Converter were used. |
