Abstract

REPRODUCTOR DE SEÑALES DE AUDIO CON CONTROL AUTOMATICO DEL VOLUMEN MAXIMO DE SALIDA. COMPRENDE UN ESTADIO FINAL, CONTROLADO POR LA SALIDA DE UN DISPOSITIVO DE CONTROL DEL VOLUMEN, PROVISTO DE UNA PRIMERA Y UNA SEGUNDA ENTRADAS, RESPECTIVAMENTE CONTROLADAS POR LAS SEÑALES AUDIO Y POR UNA SEÑAL DE MANDO. EL DISPOSITIVO PUEDE TRANSFERIR A LA SALIDA SEÑALES AUDIO CON UN VOLUMEN PROPORCIONAL A LA AMPLITUD DE LA SEÑAL DE MANDO. LAS SEÑALES AUDIO CONTROLAN TAMBIEN UNA PRIMERA ENTRADA (10) DE UN COMPARADOR (11), CUYA SALIDA CONTROLA A SU VEZ LA SEGUNDA ENTRADA (4) DEL DISPOSITIVO DE CONTROL, ESTANDO CONECTADA UNA SEGUNDA ENTRADA (12) DEL COMPARADOR A UNA FUENTE DE TENSION DE REFERENCIA (14, 15).
