Why do these things work?

It would be helpful if someone could explain why these things work the way they do. Mathematically it is clear, but what makes the diode do the right thing? - 72.58.19.66 08:09, 7 May 2006 (UTC)[reply]

For the benefit of others: LC circuit seems to answer my question. - 72.58.19.66 08:12, 7 May 2006 (UTC)[reply]

Segregate envelope from the detector

The envelope shouldn't be a subsection of the detector article, it should be a separate one. Although there is little information on the subject currently, it should be split from the detector page, so it can be expanded alone. Indomaster (talk) 23:51, 25 March 2008 (UTC)[reply]

As a long lost radio amateur and computer programmer (now moved on to legal briefs), I must disagree with Indomaster. Thirty years ago, I understood these things, but that was a long time ago. I am checking in to refresh (and hopefully update) my knowledge.

As far as separating the discussion, it would be difficult to explain to a duffer like myself what an "envelope detector" is, without explaining what an "envelope" is! If Indomaster is concerned that the envelope discussion is too mathematical for some readers, I say: let those readers skim past sections they can't understand. But don't dumb down the article. Personally, I found the explanation fully satisfactory and mercifully terse. What else would one want to add in a separate article about an envelope?

Further to "as detailed as necessary, as brief as possible" school, I believe it is good style, when throwing around greek letters and assorted gibberish, always to define one's variables.

x(t)

could stand a definition, even if as simple as "Any AM or FM signal
