Abstract: A system and method for separating aliased signals from non-aliased signals in a sampling system and method wherein the input signal includes frequency components above the Nyquist limit wherein the input signal is sampled at a first sampling rate to provide a first sampled signal, the input is sampled at a second sampling rate different from the first rate to provide a second sampled signal, and the spectral patterns of the first and second sampled signals are compared to separate the aliased signals from the real or non-aliased signals. The aliased signals can be eliminated by removing any spectral component which is not present with both of the sampling rates. While the difference in the sampling rates can be arbitrary, it also can be optimized. Additional samplings at different rates can increase the degree of the correction.
