My Experience With "Noise": Part Vb

CONDUCTED RF: Effects of RF Interference on electronic components (Work in progress)
It would be good to understand how RFI (Radio Frequency Interference) affects the functionality of the different electronic components. I saw a nice article "Integrated Circuit Susceptibility to Conducted RF Interference", published in the Compliance Engineering magazine, which describes the effect of RFI on the functionality of different active electronic components such as diode, BJT, MOS transistor, Op-amp, Digital IC individually. The link is given below:
This could serve as a good starting point for understanding and predicting what kinds of components are there at the board entry (generally IO circuit, power circuit, communication ports) which could see the RF noise. Once it could be predicted the behavior of the components in the circuit with RF Interference, necessary precautions could be taken to prevent the failures.
