Abstract

SE DESCRIBE UN CIRCUITO DETECTOR DE SEÑALES EN MOVIMIENTO ADAPTADO A APARATOS DE GRABACION Y/O REPRODUCCION DE VIDEO QUE DISPONEN DE UN CIRCUITO DE DESDOBLE DE FRECUENCIA PARA DESDOBLAR UN COMPONENTE DE UNA SEÑAL LUMINOSA DE ALTA FRECUENCIA INCLUIDA EN LA SEÑAL LUMINOSA DE UN COMPONENTE DE BAJA FRECUENCIA EN LA BANDA DE FRECUENCIA ORIGINAL, QUE COMPRENDE UN PREFILTRO (10) PARA ELIMINAR EL PORTADOR DE DESDOBLE Y LAS BANDAS LATERALES INCLUIDAS EN LA SEÑAL DE VIDEO DESDOBLADAS POR EL CIRCUITO DE DESDOBLE DE FRECUENCIA, UN PRIMER FILTRO PEINE (60) PARA FILTRAR LA SALIDA DEL PREFILTRO (10) Y DETECTAR LA SEÑAL EN MOVIMIENTO, Y UN CIRCUITO DE COMPENSACION DE ERROR PARA COMPENSAR LOS ERRORES INCLUIDOS EN LA SALIDA DE SEÑAL EN MOVIMIENTO DEL PRIMER FILTRO PEINE (60). EL CIRCUITO DE COMPENSACION DE ERROR CONSTA DE UN SEGUNDO FILTRO PEINE (61) Y DE ELEMENTOS PARA OPERAR LOGICAMENTE LAS SALIDAS DEL PRIMER Y SEGUNDO FILTROS PEINE (60, 61).
