Abstract

In order to detect the weak signal contaminated by strong background noise, and simultaneously reduce the cost of hardware system, an effective de-noising system based on Labview software platform is established. In this paper, we designed synchronous averaging algorithm-based virtual instrument programs using to implement de-noising efficiently, and extract signal successfully, which has been verified by experiment. The data is sampled by the data-acquisition card PCI 5112 made by National Instruments, and processed by the system. Using this technique, we got the signal well, and reduced background noise obviously.
