Abstract

EQUIPO DE RECEPCION DE SEÑALES VIDEO CON UN AMPLIFICADOR (10) DE GANANCIA VARIABLE PARA MANTENER LA SEÑAL VIDEO ENTRE UNOS LIMITES PREDETERMINADOS. PARA DIRIGIR LA GANANCIA DEL AMPLIFICADOR (10) SE PROVEE UN CIRCUITO (14, 18, 20, 23) QUE MANTIENE SENSIBLEMENTE CONSTANTE LA AMPLITUD DE IMPULSION DE SINCRONIZACION LINEAL. ESTE CIRCUITO COMPRENDE POR EJEMPLO UN CONVERTIDOR ANALOGICO NUMERICO (14) CON UNA SALIDA (16) DONDE UN BIT REPRESENTA EL SIGNO DEL DESVIO DE LA IMPULSION DE SINCRONIZACION LINEAL EN RELACION A SU VALOR PREESCRITO.
