Abstract
A system for performing analog-to-digital conversion comprises a sampling unit that generates multiple digital samples from an analog input signal at each recurrence of a periodic interval, and a processing unit that combines the digital samples to produce a digital output signal. In certain embodiments, the sampling unit comprises multiple analog-to-digital converters arranged in parallel, and the processing unit comprises a digital signal processor that detects outliers in the digital samples and averages any non-outliers among the digital samples to generate the digital output signal.
