Abstract
One embodiment disclosed relates to a system for modulating a plurality of micro-electromechanical (MEM) devices. The system includes a means for providing an amplitude modulation signal to each MEM device at a base frequency and a means for providing a width modulation signal at the base frequency. In addition, the system includes a clock means for providing a higher-frequency clock signal with a frequency that is a multiple of the base frequency. In this embodiment, the width modulation signal for each MEM device indicates at least one position on the higher-frequency clock signal.
