Intermodulation (IM) distortion
Intermodulation distortion is a scenario where signals from outside the monitored channel combine nonlinearly
to produce frequencies within monitored channel frequency range. This intermodulation distortion is a completely undesirable but un-
scenario in RF.
Distortions in a system are represented with the help of Taylor series
. Each term in Taylor series is represented as in formula below.
Where ft1 and ft2 are the frequencies of two different inputs signals to the system. Variable n can have any integer value.
Lets discuss following Intermodulation products:-
Second Order Intermodulation products are discussed below.
