About This Book, ]" b" F, K" L& E9 A9 L
This is not a book about how to use LabVIEW or even a book on learning digital/ k; f) B# H* ?" p
signal processing (DSP). Instead it is more of a practical guide on how to enable
! j; A% D. I) `- LLabVIEW to tackle some real-world DSP and communication problems. This

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

between obtaining theoretical knowledge and actually exercising that knowledge.5 x9 f+ n! i4 H& a1 j! U& F* x
LabVIEW provides us with an excellent set of tools for examining all sorts+ w5 N( Y' ~6 \' B

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