Impuls response match filter

WitrynaThe FIR convolution is a cross-correlation between the input signal and a time-reversed copy of the impulse response. Therefore, the matched filter's impulse response is "designed" by sampling the known pulse-shape and using those samples in reverse order as the coefficients of the filter.

A Straightforward Derivation of the Matched Filter

Witrynaimpz filters a length- n impulse sequence using filter (b,a, [1 zeros (1,n-1)]) and plots the result using stem. Note If the input to impz is single precision, the function computes the impulse response using … WitrynaMatched 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.
