Abstract
CIRCUITERIA DE CONMUTACION AUTOMATICA (1) COMPRENDE MEDIOS PARA PROCESAR SEÑALES DE ENTRADA DE MAS DE UNA FRECUENCIA INCORPORANDO INFORMACION PARA LA DERIVACION DE UNO O MAS CANALES DE AUDIO. LOS MEDIOS DE PROCESAMIENTO INCLUYEN MEDIOS DE VARIABILIDAD DE PASO DE BANDA SELECTIVA (11, 12) QUE PUEDE SER UNO DE VARIOS VALORES CORRESPONDIENTES A LA FRECUENCIA DE UNA SEÑAL DE ENTRADA. MEDIOS (14) SE PROVEEN PARA APLICAR UNA OPERACION DE DEMULTIPLEXADO SOBRE SEÑALES DE SALIDA DE LOS MEDIOS DE LA BANDA DE PASO (11, 12). EL CONTROL LOGICO (15) MANEJA LOS MEDIOS DE DEMULTIPLEXADO (14) PARA DETERMINAR SI SE HA REALIZADO UNA OPERACION DE DEMULTIPLEXADO Y DAR INSTRUCCIONES DE SELECCION A OTRO VALOR PARA LOS MEDIOS DE PASO DE BANDA (11, 12) SI NO SE HA REALIZADO NINGUNA OPERACION DE DEMULTIPLEXADO PARA UN VALOR DADO DE LOS MEDIOS DE BANDA DE PASO (11, 12).
