Abstract

EN UN SISTEMA DE MODULACION DE LA VELOCIDAD DE EXPLORACION (SUM) DEL HAZ (15) PARA UN RECEPTOR DE TELEVISION, SE APLICA UNA SEÑAL DE VIDEO (Y) A UN DIFERENCIADOR (31) SEGUIDO POR UN AMPLIFICADOR DIFERENCIAL LIMITADOR (32). UN AMPLIFICADOR CONDUCTOR (33) ACOPLADO AL AMPLIFICADOR LIMITADOR CONDUCE UNA ETAPA DE SALIDA (34) QUE SUMINISTRA CORRIENTE A UNA BOBINA SUM (26). CIERTAS SEÑALES DE VIDEO CON AMPLIO CONTENIDO DE ALTA FRECUENCIA PUEDEN TENDER A PRODUCIR DISIPACION EXCESIVA EN LOS DISPOSITIVOS DE LA ETAPA DE SALIDA. PARA EVITAR ESTO, UNA FUENTE DE CORRIENTE PARA EL AMPLIFICADOR DIFERENCIAL SE CONTROLA MEDIANTE UN VOLTAJE OBTENIDO A PARTIR DE UN RESISTOR DE MUESTRA DE CORRIENTE (116), ESTE VOLTAJE ES UNA MEDIDA DE LA CORRIENTE MEDIA A TRAVES DE LA ETAPA DE SALIDA. LA MAGNITUD DE LA FUENTE DE CORRIENTE SE VARIA MEDIANTE UN CIRCUITO DE RETROALIMENTACION LIMITADORA DE CORRIENTE (35) PARA VARIAR ASI LA SALIDA DE SEÑAL DE PICO-A-PICO DESDE EL AMPLIFICADOR LIMITADOR PARA EVITAR LA SOBREDISIPACIONDE LOS DISPOSITIVOS DE SALIDA. EL AMPLIFICADOR CONDUCTOR REALIZA UNA OPERACION DE FORMACION DE NUCLEO QUE NO SE VE AFECTADA POR LA LIMITACION DE VARIABLE.
