Per WP:MOS, articles are to avoid containing information in list or bulleted format (or keep such lists to a minimum). This article is almost exclusively in list format. Regards, --Mattisse 12:14, 29 August 2007 (UTC)
this intro paragraph is ambiguous:
"Frequency modulation (FM) and amplitude modulation (AM) are commonly used methods to modulate the carrier. In the case of single-sideband modulation (SSB) the carrier is suppressed (and in some forms of SSB eliminated). The carrier must be reintroduced at the receiver by a beat frequency oscillator (BFO)."
Does the need to use BFO only apply to SSB or to all FM and AM? I'm gonna go look for that info elsewhere now, but it'd be nice if it was clear here. I'd come back and correct this P myself, but I'm so new to this topic, I wouldn't trust myself.
BTW, I'm also curious about the entropy-information properties of the these waves and what they carry. Would it make sense to add anything about that?
Article needs work
The whole article needs to be reworked.
Why is the carrier wave usually sinusoidal? There should be some discussion of alternative waveforms, and why they were chosen. Is there some history to this? At the very least, a discussion of why sinusoidal waveforms came to be the industrial norm. Dexter Nextnumber (talk) 03:03, 17 December 2009 (UTC)
