A method of spectral-type analysis for rhythmic biomedical data is presented based on autoregressive modelling techniques. The emphasis has been on portability between data-processing machines, so that the programmes are written in FORTRAN 4 for the ICL 1900 series computers. The programmes are structured in blocks allowing for simple alteration to an interactive mode allowing the calculation and display of pre-filtering stages, model coefficients, the pole-zero plot, residuals, AR frequency spectrum, FFT of raw and filtered data. The method works on a small number of cycles and gives a direct read out of significant spectral components.
提出了一种基于自回归建模技术的有节奏生物医学数据频谱类型分析方法。重点在于数据处理机器之间的可移植性，因此这些程序是用FORTRAN 4为ICL 1900系列计算机编写的。程序按块结构编写，便于简单修改为交互式模式，可进行预滤波阶段、模型系数、零极点图、残差、自回归频谱、原始数据和滤波后数据的快速傅里叶变换的计算和显示。该方法只需处理少量周期，并能直接读出重要的频谱成分。
