Abstract

Det er beskrevet et slampulstelemetrisystem for anvendelse som endel av et måle-under-boresystem. Telemetrlsystemet utnytter moderne digitale kommunika- sjonsteknikker, innbefattende flernivåkoding. Den oppadrettede sender (18) har en kontinuerlig verdibe- stemmende slampulssender (42) som styres, id et minste delvis, ved bruk av tilbakekoblingssignaler hvorved slampulssenderen (42) arbeider lineært. Et nedadrettet system anvender samme type sender (18). Oppadrettede og nedadrettede signaler blir frekvensmultiplekset for samtidig overføring.
