Information
has gloss	(noun) electronic equipment that makes speech unintelligible during transmission and restores it at reception scrambler
has gloss	eng: In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the transmitter to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. Whereas encryption usually refers to operations carried out in the digital domain, scrambling usually refers to operations carried out in the analog domain. Scrambling is accomplished by the addition of components to the original signal or the changing of some important component of the original signal in order to make extraction of the original signal difficult. Examples of the latter might include removing or changing vertical or horizontal sync pulses in television signals; televisions will not be able to display a picture from such a signal. Some modern scramblers are actually encryption devices, the name remaining due to the similarities in use, as opposed to internal operation.

Meaning
German
has gloss	deu: Ein Scrambler (dt. Verwürfler) verwendet linear rückgekoppelte Schieberegister (LFSR) oder fixe Tabellen, um ein Digitalsignal nach einem relativ einfachen Algorithmus umkehrbar umzustellen. Erreicht wird dabei eine Änderung der Bitreihenfolge bzw. die Generierung einer neuen Bitfolge um beispielsweise bestimmte Anforderung an den Übertragungskanal zu erreichen, über welchen die binäre Datenfolge übertragen werden soll. Allgemein gesprochen wird das Digitalsignal in ein Pseudo-Zufalls-Signal mit demselben Informationsgehalt und derselben Bitrate verwandelt. Ein Scrambler basierend auf fixen Tabellen bzw. LFSR stellt wegen der einfachen und bekannten Verfahren keine brauchbare Verschlüsselung von Daten dar.
