Abstract

DISPOSICION DE CONEXION PARA CIRCUITOS COMPRESORES O EXPANSORES DE SEÑALES. LA SEÑAL PRESENTE EN UN BORNE DE ENTRADA (1) SE INTRODUCE EN UN CIRCUITO LOGARITMADOR (3) Y A CONTINUACION SE BIFURCA. EN LAS BIFURCACIONES SE COLOCAN UNOS CIRCUITOS DE TRANSMISION REGULABLES (4 Y 5) Y EN EL CAMINO SECUNDARIO, ADEMAS, UN GENERADOR (6) DE TENSION DE MANIOBRA (UST) Y DOS CIRCUITOS DE TRANSMISION (7 Y 8) CON DISTINTAS CONSTANTES (K1 Y K2). LA SEÑAL DE SALIDA SE OBTIENE EN OTRO BORNE (2).
