 This is one reason that the aviation industry, and others, have chosen to use AM for communications rather than FM , allowing multiple signals transmitted on the same channel to be heard . Phenomena similar to the capture effect are described in AM when offset carriers of different strengths are present in the passband of a receiver.

 The ability to receive multiple signals simultaneously is in some cases considered beneficial, and is one reason that the aviation industry, and others, have chosen to use AM for communications rather than FM , allowing multiple signals transmitted on the same channel to be heard . Phenomena similar to the capture effect are described in AM when offset carriers of different strengths are present in the passband of a receiver.
