Negative Positive
Title: Careless exposition
Review: This book initially presented itself as providing a thorough technical background on issues pertaining to the analysis and design of xDSL related technologies. I am afraid to say that it has not lived up to my expectations. This text, for a technical exposition, is very poorly written, incorrect derivations and equations abound, incomplete or absent explanations for derivations seem to be the norm. The authour makes conclusions without justification and leaves it up to the reader to 'guess' for him or herself. Typographical errors are the bane of any technical book and make reading it difficult and frustrating at the best of times. This book has much potential and I sincerely hope that any subsequent editions will overcome its current shortcomings.
