合成函数信号发生器的设计

Design of Synthesis Function Generator

该设计是以FPGA为核心,以C8051F005单片机作为系统控制器,利用直接数字频率合成（DDFS）技术来产生所需要的波形。并且可通过无线传输任意波形数据。通过使用芯片DAC908与AD603实现信号的输出,通过NE5532的调整,使输出信号在0~5 V内可调（负载为50Ω时）。

This design figured the FPGA as the hardcore,used the microcontroller C8051F005 as the control unit,and through the technologies of direct digital frequence synthesize（DDFS） to generate the wave needed.The output signals are produced by DAC908 and AD603,and the signals can be controlled in 0 to 5 V by the NE5532.
