基于DDS原理的任意波形信号发生器的设计

Based on DDS Principle Free Wave-form Generator Design

本文介绍了一种用AVR系列单片机ATmega8来控制FPGA实现的DDS电路,并用SRAM取代ROM的一种任意波形信号发生器的设计。用FPGA来实现DDS电路和SRAM是为了增加系统的灵活性,以便产生所需要的信号波形。

This article introduced one way of control FPGA with AVR series monolithic integrated circuit ATmega8 the realization the DDS electric circuit, and substitutes for ROM withSRAM one kind of free wave--form generator design. Realizes the DDS electric circuit and SRAM with FPGA is for increase the system the flexibility, in order to have the waveform which needs.
