Abstract
An amplifier generate harmonic noise or nuisance signals when the amplifier enters into a nonlinear amplification event. The harmonic noise or nuisance signals are spurious and a tagging circuit may tag them as such so they bypass signal processing logic and provide the same to a downstream hardware device that skips the signals tagged as spurious. The system uses a spurious signal detector and a comparator to identify nonlinear amplification events containing harmonic noise below an amplitude threshold that indicates the harmonic noise or nuisance signals as spurious to the downstream hardware device. Typically, the system is incorporated into an electronic warfare system such that the downstream hardware device effectuates countermeasures for a manned or unmanned platform.
