Abstract: An embodiment of a circuit includes an input node, a generator, a combiner, a converter, and a filter. The input node is configured to receive an input signal in a first domain, and the generator is configured to generate a periodic signal in the first domain. The combiner is configured to combine the input and periodic signals into a resulting signal in the first domain, and the converter is configured to convert the resulting signal into a converted signal in a second domain. And the filter is configured to remove from the converted signal substantially all of a frequency component of the converted signal having substantially a same frequency as a frequency component of the periodic signal.
