Abstract

DISPOSITIVO COMPRESOR DE SEÑALES PARA UTILIZACION EN UN SITEMA DE TRANSMISION DE SEÑAL, EN EL CUAL SE APLICA UNA SEÑAL COMPRIMIDA A UN CANAL DE TRANSMISION QUE ESTA CONECTADO A SU VEZ A UN EXPANSOR. CARACTERIZADO PORQUE COMPRENDE CIRCUITOS DE DEFORMACION ESPECTRAL (2), CON SECCIONES DE ALTA Y BAJA FRECUENCIA, QUE ESTAN SITUADOS EN LA VIA DE TRANSMISION DE LA SEÑAL DE ENTRADA (I) A UN COMPRESOR (4) CUYA SALIDA ESTA ACOPLADA A UN CANAL (N) DE TRANSMISION, Y PORQUE EN EL EXTREMO DE DICHO CANAL DE TRANSMISION (N) SE SITUA UN EXPANSOR COMPLEMENTARIO (6), QUE ACTUA SOBRE LA SEÑAL TRANSMITIDA, Y POSTERIORMENTE LA APLICA A CIRCUITOS (8) DE RESTAURACION DE SIMETRIA ESPECTRAL DE CARACTERISTICAS COMPLEMENTARIAS A LAS DE LOS CIRCUITOS DE DEFORMACION ESPECTRAL (2).
