ABSTRACT:
Specific noise components in an input signal are identified and isolated for processing in a desired manner. The method comprises determining an interval during which the noise component is expected to occur and isolating a portion of the input signal occurring during that interval. Determination of the interval is made by sensing noise impulses in the input signal, temporally correlating the noise impulses, and estimating the time that the noise impulses are expected to recur. The input signal can then be passed during the interval to an output signal to enhance the noise component, or the input signal can be blanked from the output signal to reduce the noise component.
