Abstract

SE DESCRIBE UN CIRCUITO DE VIA, CUYO RECEPTOR (E) REALIZA PARA LA SEÑAL DE VIA LIBRE UNA CORRELACION CRUZADA ENTRE UNA TENSION CONTINUA MEDIDA EN LA VIA (GL) Y UNA TENSION DE REFERENCIA EXTRAIDA DE LA SEÑAL DE TRANSMISION DEL TRANSMISOR (S) DEL CIRCUITO DE VIA O GENERADA INDEPENDIENTEMENTE. EL RECEPTOR (E) BUSCA EL MAXIMO DE LA CORRELACION CRUZADA Y LO COMPARA CON UN VALOR UMBRAL PREFIJADO. UNA EJECUCION PURAMENTE DIGITALIZADA UTILIZA COMO TRANSMISOR UNA FUENTE DE CORRIENTE DE VIA, QUE ES GOBERNADA POR UNA SEÑAL DE TRANSMISION MODULADA EXTRAIDA CICLICAMENTE DE UNA MEMORIA DE VALORES FIJOS. PARA EL CALCULO DE LA FUNCION DE CORRELACION CRUZADA EN EL RECEPTOR (E) Y PARA LA EVALUACION DEL MAXIMO SIRVE UNA MICROCOMPUTADORA. LA TENSION DE REFERENCIA ES GENERADA CON OTRA MEMORIA DE VALORES FIJOS PROGRAMADA DEL RECEPTOR (E) IGUAL QUE EN EL CASO DE LA MEMORIA DE VALORES FIJOS DEL LADO DE TRANSMISION.
