Patent ID: 8488663

Claim:
A method for impulse noise mitigation, comprising: a) forming an impulse noise mitigation circuit; b) forming two complex high pass filters within the impulse noise mitigation circuit; c) setting a cut-off frequencies of the two complex high pass filters to bound a frequency bandwidth of a desired signal, wherein a first of the two complex high pass filters allows frequencies higher than the frequency bandwidth of the desired signal, and wherein a second of the two complex filters allows frequencies lower than the frequency bandwidth of the desired signal; d) measuring a first signal response of the first filter; e) measuring a second signal response of the second filter; f) computing and storing a mean magnitude separately for the first signal response of the first filter and the second signal response of the second filter; g) selecting the first filter for impulse noise mitigation if the mean magnitude of the second filter is greater than the mean magnitude of the first filter; and h) selecting the second filter for impulse noise mitigation if the mean magnitude of the first filter is greater than the second filter.
