About This Book
' s; z! M- ?+ q; |' j) m% Z0 sThis is not a book about how to use LabVIEW or even a book on learning digital

book assumes that the reader has a good grasp of many of the complex issues

enough in LabVIEW to build a VI. When necessary, the book will dive into the7 B' f" t n9 D/ A
heart of signal processing topics and their implications will be explored. Certain

between obtaining theoretical knowledge and actually exercising that knowledge.

book skips all that and assumes that you already know enough about DSP to

by Rick Lyons before moving to the more advanced texts such as Discrete-Time
