WitrynaMatched Filter Abstract: The impulse response, or transfer function, of a matched filter are defined by the particular signal to which the filter is matched. Matching will result in the maximum attainable signal-to-noise ratio (SNR) at the output of the filter when the signal to which it was matched, plus white noise, are passed through it. butcher and the cow
