Abstract
(EN)
A synchronizing arrangement comprises a window circuit (WINC1, WINC2) for generating a periodic window signal (LW, RW), and a gate circuit (GC) for supplying a periodic gating pulse (Hp). The gating pulse (Hp) is related to a presented synchronizing pulse (Hs) if the presented synchronizing pulse (Hs) occurs during the window signal (LW, RW). The gate circuit (GC) generates the gating pulse (Hp) related to a leading edge of the window signal (LW) if the presented synchronizing pulse (Hs) occurs before the start of the window signal (LW, RW), and the gate circuit (GC) generates the gating pulse (Hp) related to a trailing edge of the window signal (RW) if the presented synchronizing pulse (Hs) occurs after the end of the window signal (LW, RW).

Un agencement de synchronisation comprend un circuit de fenêtre (WINC1, WINC2) générant un signal de fenêtre périodique (LW, RW), et un circuit de porte (GC) produisant une impulsion de déclenchement périodique (Hp). Cette impulsion de déclenchement (Hp) est associée à une impulsion de synchronisation présentée (Hs) si cette dernière se produit au cours de l'émission du signal de fenêtre (LW, RW). Le circuit de porte (GC) génère une impulsion de déclenchement (Hp) associée à un front avant du signal de fenêtre (LW) si l'impulsion de synchronisation présentée (Hs) se produit avant le début du signal de fenêtre (LW, RW), et une impulsion de déclenchement (Hp) associée à un front arrière du signal de fenêtre (RW) si l'impulsion de synchronisation présentée (Hs) se produit après la fin du signal de fenêtre (LW, RW).
