Abstract
Various embodiments of the present invention provide systems and methods for phase offset based spectral aliasing compensation. For example, a circuit for spectral aliasing reduction is disclosed that includes a phase shift circuit operable to phase shift an analog input signal and to provide a phase shifted analog signal; a first analog to digital converter circuit operable to provide a first series of digital samples corresponding to the analog input signal at a sampling frequency; a second analog to digital converter circuit operable to provide a second series of digital samples corresponding to the phase shifted analog signal at the sampling frequency; and an averaging circuit operable to average the first series of digital samples with the second series of digital samples to yield an average output.
