摘要：A system and method for separating aliased signals from non- aliased signals ina sampling system and method wherein the input signal includes frequency componentsabove the Nyquist limit wherein the input signal is sampled at a first sampling rate toprovide a first sampled signal, the input is sampled at a second sampling rate differentfrom the first rate to provide a second sampled signal, and the spectral patterns of thefirst and second sampled signals are compared to separate the aliased signals from thereal or non-aliased signals. The aliased signals can be eliminated by removing anyspectral component which is not present with both of the sampling rates. While thedifference in the sampling rates can be arbitrary, it also can be optimized. Additionalsamplings at different rates can increase the degree of the correction.
