A system and method of removing discrete spurious signals in cable broadband environments as well as in other RF environments employs either non-decision directed or decision directed techniques in order to remove the discrete spurious signals. The non-decision directed technique converts the signal of interest such that the spurious signal's frequency is approximately zero, filters out the converted spurious signal, and then reconverts the signal of interest back to its original location. The decision directed technique employs a decision mechanism such as a slicer to regenerate a spurious signal that is subtracted from the signal of interest containing the actual spurious signal such that the actual spurious signal is removed from the signal of interest.
