ABSTRACT:
In a phase reversed bit stream, to increase the power in the fundamental frequency and reduce harmonics, each group of positive and negative ON bits is stretched by one pulse width. A stretch of slightly less than one pulse width may also be used to prevent glitches. This invention is useful in an optical raster output scanner where a greater amount of power in the fundamental frequency will result in a grater image intensity for the same data rate.
