1. A method of processing at least one time varying electrical signal, the method including the steps of:

  • sampling the signal to provide a succession of sample values;

    sensing a rate of change of the signal;

    converting the sample values to digital form;

    writing the digitized sample values into an electronic memory device at a writing rate; and

    simultaneously reading out previously stored sample values from the memory at a rate which is different from the writing rate;

    said writing rate being automatically variable in response to the sensed rate of change of the signal.
