Impulse response of matched filter

WitrynaIt has been observed empirically that if the lter has impulse response h(t) and transfer function H(f), then ˙2 is proportional to the energy in the \signal" h(t), that is, for all choices of T 0; E[(N(T 0))2] = var(N(T 0)) = ˙2 = N 0 2 Z 1 1 jh(t)j2 dt= N 0 2 Z 1 1 jH(f)j2 df (3.1) where N 0 is a constant. Under these circumstances, the ... Witrynathe “matched filter” is the ideal linear filter for maximizing the S/N ratio f a signal amongst random noise (Robinson & Treitel,o 1980). Kirchhoff migration is a seismic processing equivalent to the matched filter. Through improved approximations of the earth’s impulse response, superior output S/N ratios, or superior
