Abstract

UN APARATO DE SINCRONIZACION QUE DETECTA EN LA PARTE CORRESPONDIENTE DE LA ONDA DE UNA SEÑAL DE VIDEO (100), LA PRESENCIA DEL EJE POSTERIOR DE UN PULSO DE SINCRONIZACION CORRESPONDIENTE, DE ACUERDO CON LA CANTIDAD DE CAMBIOS EN LA SEÑAL DE VIDEO. LA INFORMACION OBTENIDA DE LA PUNTA DE SINCRONIZACION Y LAS PARTES DE REENTRADA DEL CORRESPONDIENTE PULSO DE SINCRONIZACION, SE USAN PARA GENERAR UNA SEÑAL DE NIVEL PARTIDO (SL). UN COMPARADOR (20) QUE RESPONDE A LA SEÑAL DE NIVEL PARTIDO SEPARA UNA SEÑAL DE SINCRONIZACION (100A) DE LA SEÑAL DE VIDEO (100).
