ABSTRACT:
A mixing module includes a plurality of switched sample modules operably for generating a corresponding plurality of samples of an analog input signal in response to a control signal. A control module generates a mixing sequence and a control signal based on the mixing sequence, the control signal including a sequence of sample positions at a sampling clock rate and a sequence of scale factors, the sequence of scale factors based on an oscillation, wherein the sampling clock has a sample period and wherein the sequence of sample positions repeats at a sample position period greater than a sample interval, the sample interval equal to the sample period times the number of the plurality of switched sample circuits.
