Abstract

Circuito con amplificadores ajustables para micrófono, auricular, altavoz, transmisor de señales de selección o similares y/o con resistencias ajustables o simuladas para adaptación de la impedancia, funciones de filtración, instalaciones para la corrección de la frecuencia o para la compensación de las dispersiones o similares en aplicación en aparatos telefónicos o instalaciones o aparatos telefónicos, que funcionan conectados a líneas telefónicas o similares, con amplificadores y componentes pasivos ajustables, que se pueden ajustar digitalmente en función de palabras de datos de valor móvil codificadas binarias o que están ejecutados en técnica de circuitos integrados, caracterizado porque las palabras de datos de valor móvil se pueden introducir en memorias intermedias de valor móvil (6'', 12'', 13...) adjudicadas, alimentadas con corriente a través de hilos telefónicos (1, 2) y que se pueden almacenar allí de forma volátil o no volátil, y porque todas las memorias intermedias de valor móvil (6'', 12'',13''...) están conectadas a espacios de memoria adjudicados de una memoria central (7) no volátil o inclusoestán configuradas como componentes de la memoria central no volátil, en la que las palabras de datos de valor móvil previstas para las memorias intermedias (6'', 12'', 13''...) individuales se pueden introducir desde un transmisor de datos externo por medio de un bus de datos (39) en serie, y porque todos los amplificadores (19, 27, 37) y resistencias (6, 12, 13...) ajustables junto con sus memorias intermedias (6'', 12'',13''...) adjudicadas se pueden agrupar con su instalación de suministro de corriente (9) alimentada desde los hilos telefónicos (1, 2) así como o bien la memoria central (7) misma o las conexiones para una memoria central externa con todas las líneas de conexión (18, 32) y las instalaciones de conmutación (25, 31) en un único componente ejecutado en técnica de circuitos integrados.
