Synchronization software is measuring the frequency of digital signals commonly used sampling methods. Mainland scholars in the frequency signal cycle of software synchronous sampling done a lot of fruitful work, a more typical sampling methods: Double-rate synchronous sampling method, the error accumulated incremental method, parameter self-synchronous sampling interval Excellence in Law.
The graduation project launched by the United States NI virtual instrument software development platform as LabVIEW programming environment, LabVIEW is a common programming system, there is a complete any of the huge task of programming functions. LabVIEW using graphical programming language - G programming language, this programming method to change the programming boring interesting.
This paper described the programming environment of choice, and then discuss three main method of sampling method, and through these three kinds of graphical programming in LabVIEW algorithm to achieve. Discusses in detail the three synchronous sampling of the main ideas and methods of operation, and discussed some of these algorithms improvement measures.
