Interactive processors for the analysis and modelling of biological rhythms

An interactive processor for the analysis of biological rhythms, utilising multistage decimating i.i.r. filters, tuneable multistage lowpass, highpass and bandpass i.i.r. filters, tuneable multistage lowpass, highpass and bandpass i.i.r. filters along with forward and inverse discrete Fourier transforms, is presented. The processor is organised in such a way as to allow tailoring of the processor to fit a particular requirement; this is achieved through a computer-user dialogue. Furthermore, an interactive processor for the modelling of biological rhythms by populations of coupled nonlinear oscillators, where each oscillator can be selectively stimulated, is presented. Two examples are given to illustrate the application of the processor to analyse human colonic electrical control activity and to illustrate the main features of the modelling processor.
