I'm removing the reference to squelch from the audio engineering reference. Analog audio expansion and squelch are separate concepts. An expansion circuit is typically a feed forward circuit, which means it uses the level of the input signal to determine the level of the output - it's continuous in nature. A squelch circuit uses a completely independent input (usually the strength of the received modulation source) to mute/un-mute the output, which is discreet in nature. --[[User:Babar77|Babar77]] ([[User talk:Babar77|talk]]) 05:06, 31 October 2009 (UTC) |
