Abstract
Whereas it is not difficult to derive the impulse time parameters, T1 and T2, from a given Lightning Impulse (L.I.) generator, there has been no effective technique in making so conversely: to determine values of circuit components so that its output waveform can exactly have the given time parameters. With a conventional technique, one has to tabulate many intermediate values from curves composed from the double-exponential function despite a L.I. generator's output can precisely be described by the triple-exponential function. This paper proposes a generalised L.I. generator circuit, techniques to solve its circuit equation and a method to determine values of circuit constants to fulfil given time parameters. Performances of the Windows program based upon the developed method are also demonstrated.
