Low noise signal transmission arrangement combines random number with signal to be transmitted so distances between spectral lines in signal spectrum is significantly reduced

The arrangement has at least one unit with a pseudorandom or random number generator controlled by a control unit. The random number is combined with the signal to be transmitted by a combination unit so that the distances between the spectral lines in the spectrum of the signal to be transmitted is...

More Information
Summary:The arrangement has at least one unit with a pseudorandom or random number generator controlled by a control unit. The random number is combined with the signal to be transmitted by a combination unit so that the distances between the spectral lines in the spectrum of the signal to be transmitted is significantly reduced, whereby the amplitudes of the spectral lines reduces without the total bandwidth required for transmission increasing significantly. AN Independent claim is also included for the following: a method of transmitting digital signals between several units. Die Erfindung betrifft eine Vorrichtung zur Übertragung digitaler Signale zwischen mindestens zwei gegeneinander beweglich angeordneten Komponenten. DOLLAR A Durch eine Verknüpfung der Nutzsignale mit Zufallssignalen wird die spektrale Leistungsdichte des Signals bei gleicher Sendeleistung verringert.
