Abstract
An example apparatus that employs circuitry operating in response to digital clock signal circuitry. The apparatus includes first circuitry and second circuitry. The first circuitry produces a high-frequency digital clock signal characterized by a high frequency which carries radiative noise interference and by a modulated low-frequency digital clock signal characterized by a low frequency modulated by a first type of modulation. The second circuitry produces another low-frequency digital clock signal by combining a disparate modulation signal and a feedback signal derived from the other low-frequency digital clock signal, wherein the disparate modulation signal is characterized by modulating the feedback signal via a second type of modulation that is independent of the first type of modulation and by cancellation/blocking of the radiative noise interference manifested by the circuitry operating in response to the digital clock signal circuitry.
