Abstract
An adaptive filter is disclosed comprising a source (1) for a television signal (f), a delay device (2) for forming delay signals (v0 to v5) from the television signal, a filter combination (3) comprising at least one comb-up device and one comb-down device (3.4, 3.1) for forming filter signals (s1 to s4) from the delay signals, a mixer (5), a decision device (4) for analyzing the delay signals (v0 to v5), and a computing matrix (7) for forming weighting factors (g) for the mixer (5). A manually controllable or data-controllable setting device (8) is coupled to the decision device (4) for changing the mixing behavior in the mixer (5), which is dependent on a predetermined algorithm in the decision device (4) and/or the computing matrix (7).
