<p><P>PROBLEM TO BE SOLVED: To reduce electromagnetic interference (EMI) and radio frequency interference (RFI) caused by one computing device on another computing device. <P>SOLUTION: A device and a method reduce electromagnetic interference (EMI) and a radio frequency interference (RFI) in a computer system by using a chaotic wide band frequency modulation. A chaotic noise modulator has: a master cell which generates a control voltage in response to an un-modulated reference signal; and the slave cell which has a chaotic signal generator to generate a random noise signal and is coupled with the master cell to generate a modulated output signal in response to the control voltage. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
