本文讨论了用国产TP801单板机对随机过程作低频谱分析的实际技术。从系统构成,算法考虑到硬件接口和软件配备都作了扼要的说明。实验结果与理论有较好的符合,也满足实际估测的一定要求。它为脑电波,心电图,地震波等低频分量丰富的信息研究提供了实验手段。也为设计电脑控制的谱仪提供了实验基础。
This article discusses the practical technique of making low-frequency spectrum analysis of stochastic processes with domestic TP801 single-board machines. From the system structure, the algorithm takes into account the hardware interface and software equipment have made a brief description. Experimental results and the theory has a good match, but also meet the actual estimation of certain requirements. It provides the experimental means for the abundant information research of low frequency components such as brain wave, electrocardiogram and seismic wave. It also provides the experimental basis for designing a computer controlled spectrometer.
