Abstract

Et telemetrisystem for kommunisering i et borehull anvender to transdusere i avstand fra hverandre. Utgangene fra de to transdusere filtreres for å avkople verktøysignaler som beveger seg i motsatte retninger. Ett av de to signaler kan være et telemetrisignal, mens det andre signal kan være pumpestøy.
