ABSTRACT:
A method and apparatus for defining at least one variable parameter of an electrical pulse supplied from an RLC discharge circuit as an output to biological tissue, independently of the amplitude of the pulse, are disclosed wherein a measurement of the chronological spacing between two values of the pulse at different times is undertaken, and the chronological spacing is evaluated, with the result of the evaluation being used to define a parameter of the RLC discharge circuit.
