Multiple-pulse, pulse width and position modulation systems and methods

Abstract

Multiple pulse width and position modulation methods and systems use multiple pulse width and position modulation (PWPM) circuits driven from the same system clock and video data to provide multiple video pulses per clock period. The multiple pulse width and position modulation methods and systems separately provide extremely fine halftone structures from n-bit per pixel video data words. The halftone structures can be provided without the need for extremely high resolution raster output scanners, associated optics and high speed electronics. The multiple pulse width and position modulation system (PWPM) can produce video pulses of variable width and position within a pixel period with extremely high addressability. The pulses output from multiple, independent pulse width and position modulation (PWPM) channels can be combined to form structured multiple video pulse patterns within the video clock or pixel period from a given n bit video data word. The multiple pulse width and position modulation methods and systems can be used with cathode ray tubes (CRT), laser printers, LED BAR printhead systems, an ink jet head with an ink jet printer, a microwave transmission apparatus, data transcription devices or data encryption devices.
