Signals & Systems Demystified

I went back to school for my MS, and I'm taking a Digital Communications Theory course. Needless to say, signals and systems are very relevant to the topic, and if it's been a while since you've done anything with them and find yourself needing to re-smart yourself quick, this book is outstanding. I managed to knock off the rust, and pull a few things together as well. The math is complete, but the author don't skip steps assuming you know why he did it. You came to be demystified, not told "there's a unifying point to prove here, and we'll leave that to you as an exercise." No, he bloody well gets to the point and just tells you the relationships and so on. This isn't as in-depth as books I've seen in the past (more explicit textbooks), but if you're using this to get competent so you can do other things, it is simply outstanding. If you've got a solid grasp of calculus (it's not for dummies), then you can follow well enough to get the main point.

SIGNALS AND SYSTEMS...HARD AND NICE...WORK AS IT IS NEEDED!

As an older student going back to graduate school to learn signal and systems, I knew I was getting into trouble. My biggest problem was just trying to get the Professors or TA's or anyone to walk me through some of the equations, so I could get a feel for the math. Like baby-steps pedantic steps, and for some reason trying to get anyone to do that was nigh impossible. But Signals and Systems Demystified did just that, all the way down to the steps of reminding you a basic calculus and algebra operations. Stuff, Professors and TAs might take for granted in class, but as an older student it was all I was missing. To be walked through basic to medium problems to get a feel for the Math again. I admit I have only gone through the first part of the book, and I hope the rest is like that, but just getting those answers helped ease a lot of problems I have been having with the first few weeks of class. David McMahon has done a great thing by writing a book that takes you through the simplest of steps.

This book presents a good amount of material. It also has a good amount of solved problems for each section and usually explains what is going on. For the price I can't find anything wrong with it.

Easy understanding. The way he teaches makes it less stressful and fun to read. I'd highly recommend this book. He also has several others that are just as good. I enjoy his technique!

I love the way the information is presented, in a smart and logical order.

Not much better than my text book. Does not cover convolution to a level that was useful. DTFT is a little lax too. Apparentl;y my school is doing their own thing. can't fully blame the book, but it's not much better at "demystifying" than my text book.

Excellent textbook. It fills in many of the math steps typically left out of most used textbooks in colleges. Gerard Sagliocca, P.E. [...]

This book gives a deep view of signal and system but explains them in a very understanding way. It really filter out the unnecessary part which can confuse the beginners.
