WebUnter Optimalfilter (engl.matched filter) versteht man in der Nachrichtentechnik ein Filter, welches das Signal-Rausch-Verhältnis (engl. signal to noise ratio, SNR) optimiert.In der Literatur findet man auch häufig die Bezeichnungen Korrelationsfilter, Signal-angepasstes Filter (SAF) oder nur angepasstes Filter.Das Optimalfilter dient zur optimalen Bestimmung … WebMay 17, 2024 · Decibels are a very good way of expressing the magnitude of ratios as the scale is logarithmic, R dB = 10 log 10 ( P 1 / P 0), where in your case P 1 = P s i g n a l, and P 0 = P n o i s e. For example, if the ratio between the power of two signals is 10 10 this is simply expressed as 100dB. Signal to noise ratios are usually expressed in dB ...
