Abstract

Foreliggende oppfinnelse vedrører et system omfat- tende en fremgangsmåte og et sender-mottaker- arrangement til bruk ved sending og mottaking av ett eller flere signaler, spesielt signaler som omfatter en melding og en kode som hindrer utilsiktet bruk av meldingen, og i den hensikt å oppnå større sikkerhet mot urettmessig registrering av meldingen eller kommandoen, er det ifølge oppfinnelsen foreslått at det til meldingen og/eller koden tilføyes en tidsin- formasjon (4, 8) som i senderen (2) fremskaffes med en klokke (4), og som i mottakeren (6) kontrolleres med en synkron klokke (8).The present invention relates to a system comprising a method and a transmitter-receiver arrangement for use in transmitting and receiving one or more signals, in particular signals which comprise a message and a code preventing accidental use of the message, and for the purpose of In order to obtain greater security against unauthorized registration of the message or command, it is proposed according to the invention that a message (4, 8) is provided to the message and / or the code which is provided in the transmitter (2) with a clock (4) and which in the receiver (6) is controlled by a synchronous clock (8).
