## Sigsaly / green hornet

>> The 'noise' was provided on large shellac records which made in pairs,

I remember reading (and watching on TV) a little about a system called "Green hornet" for voice encryption; was this the same thing? Matt 16:10, 22 Mar 2004 (UTC)

What is rolling code and non rolling code

## "Scrambling" at schools

I think the para at the bottom - about scramblers used by schools to disrupt cell phone signals - is referring to a different type of scrambling (mere disruption of a signal by introduction of noise much stronger than the orig signal), not the "encryption" sense of the word that the rest of the article describes.12.32.45.119 04:49, 8 June 2006 (UTC)

You're right. Those are not scramblers, but jammers. I will amend the article. I include the old text below in case someone wants to integrate it into the jamming article: -- Securiger 22:44, 8 June 2006 (UTC)
Some modern scramblers are also used by schools. This technique is proving quite popular in the United Kingdom, where schools purchase scramblers to prevent students from using mobile telephones during lessons. There has recently been local criticism that the scramblers can be too powerful and therefore disrupt communications for adjoining houses.

Telecommunications Industry particularly the Cable Industry uses a device called a Descrambler which is obviously the opposite of a Scrambler. In my article on Cable Converter Box, I reference the term Scramble and Descramble and Descrambler several times. I wrote a brief article on Decramble to support the Cable Converter Article but when I use the term Descrambler it points to the Scrambler page without the definition in that article. Can we add a section on in this article on the subject of the Descrambler?

## Reliance on statistics of input data

Clearly, if the input data is iid, then the scrambler serves no purpose, as it merely applies a one-to-one mapping, arriving at another iid sequence. It ought to be mentioned, therefore, that a scrambler is only beneficial if the input data is not iid; in particular, the "vexatious" input sequences (e.g. strings of all zeros) must be more likely to appear than others; i.e. the statistics of the input data must be skewed in their favour.

## Merge from Randomizer

It sort of looks to me like we need two Scrambler articles: Scrambler (encryption) and Scrambler (telecommunications). I'm not familiar with the analog encryption device described in the first paragraph of the intro to this article (but nowhere else that I can see). The material in the Randomizer article is an inferior duplicate of material appearing in this article. I've not heard this telecommunications function described as a "Randomizer". I support the merge. --Kvng (talk) 15:14, 26 May 2010 (UTC)

Definitely, should be merged. Or rather, like suggested above, have two articles Scrambler (encryption) and Scrambler (telecommunications) and delete Randomizer Porttikivi (talk) 12:21, 18 January 2013 (UTC)

Pseudorandomizer might be better Ernie.cordell (talk) 04:21, 23 March 2013 (UTC)

I agree that "pseudorandomizer" might be a more accurate description, but are there actually RSes that refer to it as such? AdventurousSquirrel (talk) 07:09, 12 May 2013 (UTC)
• I merged the text from Randomizer, but I want to point out there's still a question from another editor on that talk page that hasn't been addressed yet. Also, I think we now need to address a split. I'll start a new section. AdventurousSquirrel (talk) 07:41, 12 May 2013 (UTC)

## Spelling Mistake

FULLPROOF not FOOLPROOF

Thank you, but that would be non-standard spelling, particularly in the context that the word is used here. See this explanation. AdventurousSquirrel (talk) 22:59, 15 May 2013 (UTC)

## Split

It's been suggested that this article be split between two new articles, Scrambler (encryption), and Scrambler (telecommunications). Can anyone confirm that the only text in the body of this article that deals with the encryption variety the Cryptographic section? AdventurousSquirrel (talk) 07:45, 12 May 2013 (UTC)
