Abstract

In accordance with one embodiment of the present invention a system for driving a gas discharge lamp is comprised of a bridge circuit configured to provide a pulse voltage signal, a controller configured to generate a pulse width modulated signal corresponding to a desired waveform. A filter circuit is also configured to receive and filter the pulse voltage signal provided by the bridge circuit. In one embodiment of the invention the gas discharge lamp is driven by a pulse voltage signal corresponding to a pulse width modulation signal. The pulse width modulated signal is generated corresponding to a desired waveform, wherein the desired waveform includes a sweeping frequency signal and a fixed frequency amplitude modulating signal.
