Abstract:
1. A system comprising: one or more filters configurable to have a first high-pass response and a second high-pass response, a signal magnitude determination circuitry, a comparator, and a filter response selection circuitry, wherein: said signal magnitude determination circuity is operable to measure mean magnitude, over a determined time interval, of a signal processed using said first high-pass response; said signal magnitude determination circuity is operable to measure mean magnitude, over a determined time interval, of a signal processed using said second high-pass response; and said filter response selection circuitry is operable to select which of said first high-pass response and said second high-pass response to use for suppression of impulse noise in a received signal; said comparator is operable to compare a first signal to an impulse noise detection threshold; and said first signal is a result of processing of said received signal by said one or more filters configured to have the selected one of: said first high-pass response, and said second high-pass response.
