基于PCF8591数模转换和DDS技术的信号发生器系统设计(Design of Signal Generator System Based on PCF8591 Digital-to-Analog Conversion and DDS Technology)

（1）距离算法研究和设计； （2）采用FPGA/CPLD实现。 -(1) distance algorithm and design (2) using FPGA/CPLD implementation.

数控分频器的设计数控分频器的功能就是当在输入端给定不同输入数据时，将对输入的时钟信号有不同的分频比，数控分频器就是用计数值可并行预置的加法计数器设计完成的，方法是将计数溢出位与预置数加载输入信号相接即可。-NC NC divider divider design of its function is when the input given different input data, input the clock signal will have different sub-frequency ratio, NC prescaler value can be used include parallel preset counter adder design is completed, the method is to count the number of overflow bit with preset load to the input signal phase.
