About This Book9 Y: J5 E; o. L* g5 x# p
This is not a book about how to use LabVIEW or even a book on learning digital
( I4 z! P$ k3 z- ~3 n Asignal processing (DSP). Instead it is more of a practical guide on how to enable) W2 {% _( ?3 j
LabVIEW to tackle some real-world DSP and communication problems. This4 `+ s6 @- D9 T: g* k
book assumes that the reader has a good grasp of many of the complex issues$ @" I$ O% Z- X6 _
encountered in DSP and digital communications and also is at least skilled

heart of signal processing topics and their implications will be explored. Certain
