几个不同进制的计数器的Multisim仿真，是不是很多情况下觉得电路没错为啥还仿真不出结果呢？别担心，在压缩包里有个“资料.doc”，里面介绍了几种仿真中常遇到的问题及解决的方法，相信很有帮助。-Several different hex counter Multisim simulation, in many cases is not true why did they think that circuit simulation is also not the result? Do not w

多频外差法，求绝对相位，3种方法对比。。。。。。(The multifrequency heterodyne method, the absolute phase, three methods are compared.)
