Predicting Total Harmonic Distortion (THD) in ADSL Transformers Using Behavioural Modeling

Overview As a design application, the ADSL broadband line transformer offers interesting challenges somewhat different to those in Power Supply design. In this paper the aspect of Total Harmonic Distortion (THD) as affected by the non-linear behaviour of the magnetic material in a line transformer is analysed using simulation. A mixed technology model of the line transformer is constructed and circuit simulation used to predict the level of THD for a variety of core types and configurations.

Peter Cochrane's Uncommon Sense: Education that doesn't fit

For centuries we got away with applying linear thinking and limited models to complex non-linear situations and derived adequate answers. The reality is we have little or no appreciation of the true magnitude and impact of non-linear systems.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
