Intermodulation products can be generated by carefully selecting and changing the frequency of the two input waveforms.
2.
In the case of the DJ-F1E, these dioides can create intermodulation products when the radio set is overloaded.
3.
The soft profile of the tube amplifier's distortion means that the intermodulation products of the distortion closely relate to the chord harmonies.
4.
In TV broadcasting the intermodulation products of the aural subcarrier and the main carrier appear out of the RF band of the TV channel.
5.
Rejection of unwanted signals ( images, intermodulation products ) will typically be much greater than a consumer-type general coverage or broadcast receiver.
6.
The tone frequencies, as defined by the Precise Tone Plan, are selected such that harmonics and intermodulation products will not cause an unreliable signal.
7.
When VF and the aural signal modulate the same carrier the inevitable non-linearity of the electronic circuits cause unwanted signals which are called intermodulation products.
8.
The internal diodes of an SWR meter may generate objectionable harmonics when transmitting and produce intermodulation products during reception, if it is left in the system after measurement.
9.
For example, intermodulation products of channel 7 appear in channel 5, 6, 8 and 9 . That is why notch filters are used in intercarrier system.
10.
This also reduced a falsing problem that existed in larger systems where mobile radios would open up on other users tones as well as intermodulation products occurring in large metropolitan areas.
