Abstract
EMI spur interference is reduced in a system where the desired signal has periodically repeating components without destructively interfering with the repeating components. The frequency of the spur interference is determined (203) and fed to a notch filter (201) so as to center the notch at the frequency of the spur interference. Determination of the frequency is scheduled (601) to avoid cancellation of desired periodically repeating components of the signal.
