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

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.)
