How does it work?

The article doesn't explain why the weaker station is rejected or what a "receiver limiter" is. 08:17, 23 February 2007 (UTC)

Similarly it would be great to know why AM radio transmissions are not subject to this effect, as the article states. -- TripleF (talk) 14:50, 23 May 2009 (UTC)Reply

As far as I remember "Capture Effect" is basically inherent in ALL FM modulation sytems. I think it can be proven mathematically, I can't think of any other way. Apart from experimentally.

Each FM signals frequency is changing constantly. An AM signals center frequency remains the same. An AM receiver sees the sum total of any sigals presented to it's antenna. If that signal consists of multiple transmissions on the same frequency, they will all be heard. There is no way of telling them apart. Not a good explanation, but the best I can give for now.

Compared to (for example) FM Limiter & Capture Ratio, by Dietmar Rudolph, this Wikipedia article does nothing to explain FM capture effect. -- AHMartin (talk) 20:51, 26 January 2012 (UTC)Reply

I think the section explaining AM's immunity to the effect needs to be clearer. —Preceding unsigned comment added by 96.230.232.9 (talk) 04:51, 7 March 2011 (UTC)Reply

This article is more than half on AM not having a capture effect. I somewhat understand the FM capture effect, but came here to remember the effect on S/N ratio for FM signals. Specifically, the S/N ratio after demodulation is much higher than before demodulation, for similar reasons. Or, in other words, the capture effect removes lower amplitude signals as noise. But I forgot the details in terms of S/N. Gah4 (talk) 23:29, 25 May 2018 (UTC)Reply
