摘要
根据直接数字频率合成技术,以FPGA为核心,设计了一种便携式多功能信号发生器,可产生正弦波、方波、三角波、锯齿波等信号。通过仿真及硬件实验表明,该信号发生器具有信号频率误差小、分辨率高、体积小、质量轻等优点。
According to direct digital synthesis（DDS）,a portable multi-functional signal generator was designed based on FPGA,which could output sinusoidal wave,square wave,triangle wave and sawtooth wave.Simulation and hardware experiment show that the portable multi-functional signal generator has some advantages,such as high accuracy and high resolution with small size.
