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.

Matched filters are commonly used in radar, in which a known signal is sent out, and the reflected signal is examined for common elements of the out-going signal. Pulse compression is an example of matched filtering. It is so called because the impulse response is matched to input pulse signals.
