The present invention detects, determines, and mitigates signal-path processing errors. An extracted and inverted reference signal is compared to the carrier signal produced by various functional components to determine the error introduced to that signal by functional components. After the signal has been processed by various signal-processing components, the signal can once again be compared to the inverted reference signal so that a signal-path processing bias can be determined. Using that determination, a signal modification can be initiated to substantially reduce or eliminate all signal-path processing error.
