Arrangement for steepening and reference level position in video signals

摘要

a processing arrangement for video signalsa television receiver includes a body (65) for the production of a versteilerungskomponente, with a video signal to produce a versteilerten videosignals are combined, and a steuerschaltung (30, 40) on the versteilerte video signal during predetermined regelungsinterv all addresses of a bezugspegel videosignals automatic rules.the versteilerungskomponente during the mentioned regelungsintervalle subdued (66) to prevent unwanted signals including noise in the steuerschaltung raises the otherwise by the versteilerungssignal producing facility increased and a ausgangsseit an output voltage of the steuerschaltung would distort.in a system in which the steuerschaltung in a feedback loop with a versteilerungsschaltung is arranged, which is commonly used is the attenuation to the feedback loop against oscillation to stabilize.
