Telecommunications: Twisted Pair Cable Noise Immunity

This online, interactive lesson provided by Wisc-Online and the National Science Foundation explains how data is transferred through electrical conductors and the various configurations in which one can find these conductors. This slideshow goes into detail about the reasoning behind twisting cables – to reduce crosstalk and EMI (electromagnetic interference). The illustrations and animations are extremely helpful along side the clearly defined terms and descriptions. This is a great resource for students or teachers looking to better understand today’s technology.
