Abstract

L'invention propose un procédé et un montage permettant une correction de réponse en fréquence rapide lors de la reproduction de signaux de télévision en couleurs enregistrées magnétiquement. Le montage comprend un élément de correction de réponse en fréquence, dont la caractéristique de réponse en fréquence est fonction du niveau du signal extrait de la bande magnétique.The invention provides a method and an arrangement for rapid frequency response correction when reproducing magnetically recorded color television signals. The assembly includes a frequency response correction element, the frequency response characteristic of which is a function of the level of the signal extracted from the magnetic tape.
