Abstract

Pulse width modulation of signals, such as provided to a driver in a laser printer, is phase locked to a beam detect signal. In addition, it must permit continuously variable, arbitrarily small pulses at extremely high speeds. This invention describes a novel method and system using multiple streams of variable phase clocked outputs. The variable phase clocked outputs are combined with a clock generator to achieve these goals at low cost. As a result, the pulse width modulated signals provide continuously variable selectable pulse widths at extremely high speed.
