摘要
提出了一种基于PX I总线的正弦信号失真度测量方案,该方案利用高精度数据采集卡对被测信号进行数据采集,应用基于遗传算法的曲线拟合方法对采集数据进行处理。实验证明该方案精度高,扩展性好,具有很高的应用价值。
This paper presents a project of sine signal distortion measurement based on PXI bus. The project applies high accurate data acquisition device to acquire data and the curve fitting based on the genetic algorithm to process data acquired. Experiment indicates that the project possesses of high accuracy, good expansibility and high application value.
