Narrowband Frequency modulation is used exclusively, so that the capture effect will select the stronger of two transmitters wherever one predominates.
12.
Phenomena similar to the capture effect are described in AM when offset carriers of different strengths are present in the passband of a receiver.
13.
The capture effect can occur at the signal limiter, or in the demodulation stage, for circuits that do not require a signal limiter.
14.
FM receivers are subject to the capture effect, which causes the radio to only receive the strongest signal when multiple signals appear on the same frequency.
15.
For example, the aviation glideslope vertical guidance clearance beam is sometimes described as a " capture effect " system, even though it operates using AM signals.
16.
The channel capture effect creates a situation where one station is able to transmit while others are continually backing off, thus leading to a situation of short-term unfairness.
17.
The two stations may also have their actual carrier waves synchronized via GPS for further stability, and to avoid phase cancellation, but as a matter of physics it is impossible to avoid the switching caused by FM's capture effect.

:: All FM ( but not AM ) receivers are subject to Capture effect which is a kind of AFC, not a welcome one when interfering signals are strong . talk ) 23 : 30, 18 June 2014 ( UTC)

Conversely, Fred Topel of CraveOnline gave the film a positive review, saying that the film " will shock you to your core " and that the last 10 minutes " are the most exciting of any summer movie, and without motion capture effects ."

In FM systems where the IF stage gain is very high and the stage is designed to be linear, it is likely that if the unwanted signal is at least 10 dB weaker than the wanted signal that the capture effect will result in the receiver ignoring the unwanted signal.
