About This Book
( I8 i4 j/ Q) Y4 ~4 SThis is not a book about how to use LabVIEW or even a book on learning digital

* N0 g. ]4 v! w" U" qLabVIEW to tackle some real-world DSP and communication problems. This& g8 U" q- p2 I
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 the

topics will be explained in enough detail so that the reader will know there is

between obtaining theoretical knowledge and actually exercising that knowledge.
