Abstract
A signal processing system includes a phase locked loop for locking a largest sine wave phase and frequency element of an incoming analog signal; an amplitude estimator for estimating a maximum amplitude of the incoming signal; a multiplier for multiplying the estimated largest sine wave phase and frequency element by the estimated maximum amplitude to provide an estimated largest sine wave component; and a subtractor for subtracting the estimated largest sine wave component from the incoming signal to provide a diagnostic signal.
