This book is intended for those who work in or provide components for industries that use digital signal processing (DSP). There is a wide variety of industries that utilize this technology. While the engineers who implement applications using DSP must be very familiar with the technology, there are many others who can benefit from a basic knowledge of its' fundamental principals, which is the goal of this book—to provide a basic tutorial on DSP.

Editor's Note: This extract is Part 1 of a seven-part series from this book.

Downloaded! Took a long time. Good but brief summary of the 1st four chapters. This looks like a great intro to DSP.

Easy to read, easy to follow, it surely is effective on reminding (some of) us what we learned in school. Though, I've always questioned why did Nyquist came out with the term “aliasing”, it's not that intuitive to me... perhaps because english isn't my first language but... wouldn't have been better something like a “phantom frequency” or “mirrored signal” or... well... you get what I'm saying right? :-)

I understand exactly what you mean. I approach it differently, when a higher frequency signal shows up as lower frequency signals it is assuming an alias. It is masquerading as a different signal( or signals) and assuming an alias, or as it was called aliasing. It is an alias because the actual signal is there and could be measured, so it is not a phantom, the real signal is still there, just assuming an alias to ruin your day.

When I was at school we called it a "beat frequency", because at AF it "beat time" as you would to music. I wondered for years what "aliasing" meant - I assumed it was something way above my head - until I came across a definition somewhere and realised it was just my old friend "the beat" after all!

MikeLC Posted Oct 31, 2010

Like Luis, I've enjoyed the reminder. I'm actually still going through this course, just a bit at a time. Back in my grad school days, studying Computer Vision, we applied DSP to graphical signals and the aliasing made sense to a point. But "maxm"'s comment on an alias being a masquerading signal is excellent. Also, Ian's "beat frequency". I'd never thought of two slightly out of tunes strings as a form of sampling before! But it's true! Thanks.

Hi. Ian's notion that spectral aliasing is related to "beat frequency" (the sum of two audio sine waves that are close in frequency) is not correct. What people call "beat frequency" can happen in the analog world (guitar strings) but aliasing can only happen in the worlds of sampled data (digital signals). Aliasing cannot exist with analog signals. By the way, what people call "beat frequency" is actually an audio illusion. When you simultaneously pluck a 400 Hz guitar string and a 410 Hz guitar string, the resultant audio signal contains *NO* spectral energy at 10 Hz. The real story about "beat frequency" can be found at: http://www.dsprelated.com/showarticle/189.php. [-Rick-]

The summary chapters were very good indicating a strong partnership with application learning, which is where most engineers want and need materials.

This material has the academic level. I believe that the concepts should contain practical examples of actual day-to-day. Still, it's very good!

Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time, discrete frequency, or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals. consultant

It's actually a lot easier than I thought it would be. I first heard about this system from a group of med students. They were working on an application that could provide a systematic program for long term asthma relief for some patients in their database. That really got my attention.

*An impressive share, I just given this onto a colleague who was doing a little analysis on this. And he in fact bought me breakfast because I found it for him.. smile. So let me reword that: Thnx for the treat! But yeah Thnkx for spending the time to discuss this, I feel strongly about it and love reading more on this topic. If possible, as you become expertise, would you mind updating your blog with more details? It is highly helpful for me. Big thumb up for this blog post! Content Ferret

Omg ! I really have no idea how I cleared this paper in my engineering years. This part was such a pain in the back for me. well I have to admit in spite of all this it’s a leading factor why we could use majority of the technologies made possible that we use now. fix microsoft errors
