学习数控分频器的设计、分析和测试方法。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 crossover study design, analysis and testing methods. NC divider function is that when the input given different input data, input the clock signal will have a different frequency than, NC divider is in parallel with the meter values can be preset in addition counter design completed, method is to count the number of overflow bit and pre-loaded connecting the input signal can be.
