Apparatus for detecting periodicity in a non-sinusoidal waveform comprises a peak detector for detecting peaks in a waveform, a signal generator for generating a succession of signals corresponding to detected peaks and a signal analyser including a signal plotter arranged to input a succession of signals corresponding to detected peaks and to plot time duration since input of each signal against a logarithmic to the base 2 representation of time. |
