Hong Wu Qin, Nian Feng Li, Chun Feng Li · Advanced materials research · 2013
This paper describes a software and hardware analytical complex of spectral characteristics. The analysis complex includes the research of the signals with the ability to create a database for identification. Analysis of the spectral characteristics by using special instruments - spectrum analyzer. Presents the results of the evaluation of scientific and practical significance of the software developed. Spectral data multichannel analyzer spectrum was obtained with DAQ-device National Instruments.
