Abstract

CIRCUITO GENERADOR DE SEÑALES DE SINCRONIZACION. COMPRENDE UN GENERADOR QUE ORIGINA UNA SEÑAL CADA VEZ QUE APARECE EN UNA SEÑAL ENTRANTE UN IMPULSO CON VALOR INTERMEDIO ENTRE EL NIVEL DE REFERENCIA Y EL NIVEL DE PICO. DICHA SEÑAL, CUYO VALOR ES UNA MEDIDA DE LA DURACION DE DICHO IMPULSO, ES COMPARADA CON UN PRIMER VALOR DE UMBRAL. DURANTE LA APARICION DE LOS IMPULSOS DE SINCRONISMO DE LINEA, LA SEÑAL DEL GENERADOR DE SEÑAL ES INHIBIDA EN TANTO NO SE HAYA ALCANZADO TODAVIA EL PRIMER VALOR DE UMBRAL. LA SEÑAL PROCEDENTE DEL GENERADOR DE SEÑAL ES COMPARADA CON UN SEGUNDO VALOR DE UMBRAL, QUE ES UNA MEDIDA DE LA DURACION DE IMPULSO QUE SUPERA A LA DURACION CORRESPONDIENTE DEL PRIMER VALOR DE UMBRAL. LA SEÑAL DE SINCRONISMO DE CAMPO ES GENERADA TAN PRONTO COMO SE ALCANZA EL SEGUNDO VALOR DE UMBRAL.
