Abstract

EL PROCEDIMIENTO DESCRITO SIRVE PARA SU UTILIZACION EN LA TRANSMISION DE DATOS ENTRE ESTACIONES (Q,R) DE PREGUNTA Y DE RESPUESTA, DONDE LA ESTACION (R) DE RESPUESTA DISPONE CON PREFERENCIA DE UNA SUPERFICIE DE ELEMENTO (OFW) DE ONDA ACUSTICA CON UN SUBSTRATO ADECUADO PARA SUPERFICIE CONDUCTORA DE ONDAS ACUSTICAS. LOS IMPULSOS DE PREGUNTA DE BANDA ESTRECHA EMITIDOS POR MEDIO DE LA ESTACION (Q) DE PREGUNTA SE MODIFICAN EN LA ESTACION (R) DE RESPUESTA DE TAL MODO QUE EL ESPECTRO DE FRECUENCIA DE LOS IMPULSOS DE INTERROGACION MODIFICADOS DESCANSAN AL MENOS PARCIALMENTE FUERA DEL CAMPO DE FRECUENCIA DE LOS IMPULSOS DE INTERROGACION NO MODIFICADOS. LOS IMPULSOS DE INTERROGACION SON, POR EJEMPLO, GUIADOS A LA SUPERFICIE ACUSTICA DE ELEMENTOS (OFW) DE ONDA EN LA ESTACION (R1) DE RESPUESTA, POR EJEMPLO, POR MEDIO DE LA ENTRADA INTERDIGITAL DEL TRANSDUCTOR (IDWI) Y REFLEJADOS COMO IMPULSOS DE RESPUESTA A LA ESTACION (Q1) DE INTERROGACION DONDE LOS COMPONENTES DE SEÑAL QUE SE ENCUENTRAN EN EL CAMPO DEFRECUENCIA DE LOS IMPULSOS DE RESPUESTA SON RECHAZADOS. LAS SEÑALES DE RESPUESTA PUEDEN SER DE ESTA FORMA PROCESADAS SIN QUE OCURRAN INTERFERENCIA DEBIDO A LOS IMPULSOS DE INTERROGACION EMITIDOS POR OTRA ESTACION (QX) DE INTERROGACION.
