In a particular embodiment, a circuit device includes an input to receive a pulse-width modulated (PWM) signal and an output to send a modulated PWM signal. The circuit device further includes a pulse edge control circuit coupled between the input and the output. The pulse edge control circuit receives the PWM signal via the input and includes a control input to receive a modulation control signal. The pulse edge control circuit is adapted to modify the PWM signal to provide the modulated PWM signal with suppressed carrier power and associated harmonics to the output based on the modulation control signal. The circuit device further includes a modulation sequence controller adapted to provide the modulation control signal via the control input. The modulation control signal selectively controls a sequence of the modification of the PWM signal to selectively alter an output power spectrum of the modulated PWM signal.       Recently Added Patents Bow making template Bearing device for a wind turbine nacelle Low noise amplifier and mixer Process and apparatus for converting high boiling point resid to light unsaturated hydrocarbons Sole Flow control liner system Memory module including parallel test apparatus   Randomly Featured Patents Photographic member with flexibilizer material Fiber optic cables with strength members Sculpture and method for constructing Multibeam antenna Endless microcassette tape Contamination protection system for endoscope control handles Replaceable circuit board mounting system in outer rotor motors Combined beverage container and drinking tube Method and system for generating antenna selection signals in wireless networks Primitive cell colony stimulating factors and lymphohematopoietic progenitor cells © 2006-2008 PatentGenius.
