Abstract

UN AMPLIFICADOR RESPONDE A UNA FUENTE DE SEÑAL (38) Y COMPRENDE AL MENOS VARIAS ETAPAS DE SALIDA DE ENERGIA (40.140.48) ACTIVADA SOLAMENTE EN UNO DE LOS DOS ESTADOS BINIVEL CONTROLADO EN RESPUESTA AL VALOR DE LA FUENTE, LAS SALIDAS BINIVEL ASOCIADAS A LOS ESTADOS BININVEL DE LAS VARIAS ETAPAS SE SUMAN JUNTOS PARA SER UNA ONDA DE SALIDA QUE ES UNA FUNCION DE PASO PREDETERMINADA DE LA SEÑAL DE FUENTE. EL AMPLIFICADOR TIENE MEDIOS (105) PARA DETECTAR UN FALLO DE DICHAS ETAPAS MIENTRAS QUE EL AMPLIFICADOR RESPONDE A LA SEÑAL DE LA FUENTE Y MEDIOS (121, 125, 126, 127, 133) EN RESPUESTA A UN FALLO QUE ES DETECTADO POR EL MEDIO PARA DETECTAR PARA CONTROLAR LAS ETAPAS DE SALIDA DE ENERGIA DE MODO QUE LA ONDA DE SALIDA PERMANEZCA EN LA FUNCION DE PASO PREDETERMINADA A PESAR DE LA PRESENCIA DEL FALLO.
