Abstract

SE DESCRIBE UN METODO Y APARATO EN LOS SISTEMAS TELEFONICOS MOVILES QUE INCLUYEN ESTACIONES DE BASE PROVISTAS DE UNA GRAN CANTIDAD DE MODULOS DE RESONANCIA, PARA AJUSTAR INDEPENDIENTEMENTE CADA MODULO A SU PROPIA FRECUENCIA PARA RECIBIR Y TRANSMITIR SEÑALES TELEFONICAS A ESTA FRECUENCIA . EN CADA MODULO EXISTE UN MEDIO SINTONIZADOR CONTROLADO EN SU POSICION DE RESONANCIA DADA EN RELACION CON LA FRECUENCIA DE LA SEÑAL ENTRANTE. LOS MEDIOS SINTONIZADORES (2) DEL MODULO DE RESONANCIA SE OPERAN MEDIANTE UNOS MEDIOS DE TRANSMISION ELECTROMECANICA CONECTADOS PARA OBTENER TENSION DE TRANSMISION A TRAVES DE UNOS MEDIOS DE COMPARACION DE FASES (7), FORMADOS DE FORMA QUE LA TENSION DE TRANSMISION PASA SOLAMENTE CUANDO DOS SEÑALES DE ENTRADA A LOS MEDIOS DE COMPARACION DE FASE, DIFIEREN EN LA FASE. UNA LINEA DE SEÑALES AL MODULO DE RESONANCIA ASI COMO UNA LINEA DE SEÑALES DESDE LA SALIDA DEL MODULO SE CONECTAN A LOS MEDIOS DE COMPARACION DE FASES. CUANDO AMBAS SEÑALES ESTAN EN FASE, LA TENSION DE TRANSMISION ES 0, LOS MEDIOS DE TRANSMISION ESTAN ESTACIONARIOS Y LOS MEDIOS SINTONIZADORES (2) MANTIENEN EL MODULO DE RESONANCIA AJUSTADO EN LA RESONANCIA HACIA LA SEÑAL DE ENTRADA. TAMBIEN SE DESCRIBEN LOS MEDIOS DE AJUSTE (3) PARA CONTROLAR LOS MEDIOS SINTONIZADORES (2).
