SUPPRESSION OF A PHASE-SENSITIVE SPECTRAL COMPONENT FROM A SIGNAL

摘要

A method and apparatus for suppressing a phase-sensitive spectral component from a given signal. A phase and amplitude-sensitive blocking pulse is generated at the frequency of the spectral component. This blocking pulse is subtracted from the signal and the unsuppressed portion of the spectral component is used to adjust the phase and amplitude of the blocking pulse, so as to more completely eliminate the spectral component from the signal.
