摘要
介绍了一种DDS(直接数字频率合成器)电路的基本工作原理,以及以DDS为核心的信号源的硬件、软件设计电路和设计方法,并简单介绍了EPROM的内部设计原理,还对实验过程和试验结果进行了分析比较。
It introduces the basic principle of the direct digital frequency synthesizer（DDS） ,with the design proposal and circuit of hardware as well as the method of design and the train of thought of the software of the signal source by using DDS. Furthermore simply introduce the principle of the EPROM. It analyses the process and result of the experiment.
