What is the term used to refer to a reduction in receiver sensitivity caused by unwanted high-level adjacent channel signals?
⢠Receiver sensitivity in marine radios (how weak a signal the receiver can still detect) ⢠Effect of strong nearby/adjacent channel signals on a receiver ⢠Difference between desensitizing, intermodulation distortion, and overloading as radio problems
⢠Ask yourself: which term specifically describes the receiver becoming less able to hear weak signals because a strong signal on a nearby frequency is present? ⢠Which option refers more to the mixing/creation of spurious signals, rather than just making the receiver less sensitive? ⢠Which term is normally used for FM receivers becoming quieter (less noise) as signal strength increases, and is that what the question is asking about?
⢠Verify which option is directly defined in radio theory as a reduction in receiver sensitivity due to strong signals on adjacent channels. ⢠Check that you are not confusing distortion of signals (changing their shape or creating extra signals) with simply making the receiver âdeafâ to weak ones. ⢠Confirm that quieting usually refers to reduced noise with stronger desired signal, not a problem caused by unwanted adjacent-channel signals.
