Abstract
EN UN APARATO DE TELEFONIA MOVIL, UN SUMADOR (17) CALCULA UNA SUMA DE (A) UNA SEÑAL DE AUDIOFRECUENCIA QUE SE COMPONE DE UN COMPONENTE DE SEÑAL DE HABLA Y UN COMPONENTE DE SONIDOS Y (B) UNA SEÑAL GENERADA QUE TIENE UNA FRECUENCIA FUERA DE SONIDO, COMO 6 KHZ, Y UN NIVEL PREDETERMINADO Y SUMINISTRA UN COMPRESOR (21) CON LA SUMA COMO SU SEÑAL DE ENTRADA. EL SUMADOR Y EL COMPRESOR PROPORCIONAN UNA GANANCIA VARIABLE INFERIOR A LA SEÑAL DE AUDIOFRECUENCIA DE UN RANGO DE NIVEL INFERIOR A LA DE RANGO DE NIVEL SUPERIOR. ALTERNATIVAMENTE, EL COMPRESOR SOLO, PROPORCIONA LA GANANCIA VARIABLE INFERIOR A LA SEÑAL DE ENTRADA DEL RANGO DE NIVEL INFERIOR. UNA SEÑAL COMPRIMIDA ES TRANSMITIDA A UNA ESTACION BASE COMO UNA SEÑAL DE RADIO Y ES EXPANDIDA. PARA UTILIZAR EN UN SISTEMA DE COMUNICACION POR RADIO DEL TIPO REVELADO EN LA PATENTE DE ESTADOS UNIDOS N GENERADA PUEDE SER PROPORCIONADA POR EL TONO AUDIBLE DEL SUPERVISOR O POR EL TONO DE REFERENCIA.
