Answering a genuine need, Wilmshurst's book is the single most illuminating contribution to and understanding of the range of techniques for efficient signal recovery from electronic noise. It stands apart from the other books and articles by virtue of the originality, clarity, and systematic exposition of every aspect of enhancing an electrical signal. It is an exceptional achievement, written in an outstandingly refreshing manner that should alter the ways in which electronic instrumentation is understood and taught at advanced undergraduate or graduate level and beyond. In short, anyone wanting the ins and outs of signal retrieval should get a copy.
