Abstract
A method and apparatus are disclosed for generating a high current, high-voltage pulse suitable for driving a shock wave source of the type which generates a shock wave in an acoustic transmission medium. In the apparatus, a signal generator generates a low-voltage signal having an energy content sufficient for generating the shock wave, and a pulse-shaping network, connected between the signal generator and the shock wave source, as a transfer function which shortens the signal duration of the low voltage signal from the signal generator so that the low-voltage signal is converted into a high voltage pulse suitable for driving the shock wave source. The high-voltage pulse has an energy content substantially the same as that of the low-voltage signal.
