Comparative Study On The Field Of Time-Frequency Measurement And Control Based On Lab View

LabVIEW(Laboratory Virtual Instrument Engineering Workbench) is a graphical programming language development environment, it is widely used in industry, academia and research laboratories. It is seen as a standard data acquisition and instrument control software. This paper studied on high-precision frequency measurement methods based on a series of new principles and new methods, and then proposed two algorithms based on measuring the frequency of LabVIEW. Combined with modern measurement theory, the three-point method and energy rectangular balance, this algorithm improved signal processing capabilities LabVIEW. The experiment verified the correctness and feasibility of two methods, which can both effectively reduce the frequency measurement error and noise; and can be used in different fields.
