Chaotic wide band frequency modulator for noise reduction

摘要

The embodiments of the invention relate to apparatus and method for reducing electromagnetic interference (EMI) and radio frequency interference (RFI) in computer systems via a chaotic wide band frequency modulation. The chaotic noise modulator, in one embodiment, comprises: a master cell to generate a control voltage corresponding to an un-modulated reference signal; and a slave cell having a chaotic signal generator to generate a random noise signal, the slave cell coupled with the master cell and operable to generate a modulated output signal in response to the control voltage.
