✦ Synopsis

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 axe 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.
