intermodulation interference

[‚in·tər‚mäj·ə′lā·shən ‚in·tər′fir·əns]
(electronics)
Interference that occurs when the signals from two undesired stations differ by exactly the intermediate-frequency value of a superheterodyne receiver, and both signals are able to pass through the preselector due to poor selectivity.

When more than two carriers are present in a channel, third-order intermodulation interference can be created by the multiplication of three fundamental carriers; this is called carrier triple beats (CTB).
Unlike third-order intermodulation interference, CTB signals can overlap each other and add noncoherently.
A large number of connectors display good intermodulation characteristics in a static state but, when dynamically tested, are subject to intermodulation interference up to 40 dB higher than in the static state.
