Abstract

RECEPTOR DE BANDA LATERAL UNICA. LA SEÑAL DE ENTRADA (V<054><009>) PASA A UN FILTRO (34) Y A UN MEZCLADOR DE FRECUENCIAS (36), DONDE SE COMBINA CON UNA SEÑAL PORTADORA (V<050>) PRODUCIDA POR UN SINTETIZADOR PORTADOR (38) A PARTIR DE UNA SEÑAL (V<055><056><037>) PROCEDENTE DE UN GENERADOR DE REFERENCIA (40). EL RESULTADO ES UNA SEÑAL DE FRECUENCIA INTERMEDIA (V<054><037>) QUE ES SEPARADA EN UN FILTRO DIVISOR (42) EN DOS SEÑALES (V<057>, V<058>) QUE ALIMENTAN UN AMPLIFICADOR CONTROLADO DE GANANCIA AUTOMATICA (48). LAS SEÑALES AMPLIFICADAS ATRAVIESAN UN DEMODULADOR (54) Y UN FILTRO DE SALIDA, PRODUCIENDO UNA SEÑAL DE SALIDA DE AUDIO (V<033><052><059>).
