I downloaded it and read it too, it mirrors the intro course I once taught on digital circuit design almost exactly. It teaches the essential stuff as it was 35 years ago or so. However, I doubt that anyone has used a Karnaugh map in quite some time, there's a lot of this book that would seem pretty superfluous today.
Well, as a kid, mumble, mumble years ago I had a book that I think was called simply "Digital Electronics". I talked a bit about transistors and how they can be used as switching devices, it introduced AND, OR, NAND, NOR, XOR etc and how they can be made from transistors. It then built up digital circuit blocks like flip-flops, decoders, counters, adders etc. It discussed using the new fangled 74 series devices were only just becoming available for young nerds at home.
I recall seeing the circuit of the J-K Flip flop using NOR gates in that book for the first time ever, wow it was inspirational, it's burned into my retina still.
I like to think there is a place in the world for such basic books for kids sill today. Perhaps this is one.

Best digital book I started with was in 197xxx and that was Don Lancaster's "TTL Cookbook". That and Comer's "Digital Logic and State Machine Design". As to mapping, used it "a while back" for EPLDs. Not useful FPGA or other programmable devices?

My high school introduction to digital electronics was a step by step work book that covered the same basic material. Cannot recall the exact title but it was something along the lines of "A Programmed Text for Digital Electronics". It was an excellent introduction, and imo the fundamental knowledge I got from it was priceless. Everyone involved in computers and electronics would benefit from understanding it at such a fundamental level.

I still have the copy of the TTL Cookbook I bought many decades ago! I read through that over and over and over again!
And any of Forrest Mimms books at Radio Shack may cover the topics...
When Kat wanted to learn some electronics, we scored some good Ebay deals on the RadioShack Electronics Learning Lab, SensorsLab, and 300 in One Electronic Project Lab kits.
So we have the 3 included books by Forrest Mims:
"Basic Electronics" (transistors and integrated circuits) Workbook I
"Digital Logic Projects" Workbook II
"Electronic SensorsLab"
We've done a few of the projects with the kits like blinking LEDs and made a working Volt Meter, but have a long way to go to get through them all (especially with the Parallax Activity Bot now taking precedence). Are most of the things in those Forrest Mims books still pretty relevant today? Looks like 2000 - 2001 on the copyrights. Or have things sailed on in the past 15 years since they were printed and we should get something more updated?

copyright 2000 to old? Nah, not for these. They're fairly basic. I have a couple and the info is still very useful. Learn from them and build from there. Stuff changes and new stuff emerges that won't be in them, but the basics don't change much if at all.

Ok that sounds like the course I too taught for a short while, nearly 30 years ago in my case.. so I don't really need to lose sleep over not catching the free download. Thanks!
Nice that you found that (thanks for the links!) but that too is a very old method. My point was that almost no one has a need to minimize logical expressions these days as most designers just use a micro or programmable gate array of some type and the problem becomes one of programming and/or compiler optimization of a complex expression. In theory the people that design micros might still need to do this, but I'm sure that their tools do this for them. (I guess there might be a need for this in some super time critical processing too.)
Still the idea of logical expression minimization is important and should be covered in a modern basic digital design course, but having students spend a lot of time with Karnaugh maps (or Quine-McCluskey tables) would be pointless.
Ha! That's the smart kids. The others seem to have chemical means of minimizing their logic...
wass,
Now you got me. What's a more recent method than Quine-McCluskey? I might need it if I ever get around to building that CPU out of relays/transistors that I sometimes day dream about.
I guess you are right, I would hope my FPGA tools are minimizing things for me as best they can (They certainly take long enough about it ). Still, we have calculators but it's probably a good idea to learn how to multiply for yourself. Similarly I would hope that students of logic design spend a little time to learn these things.
Watch out for Kindle formats. Seems some of them do not view on win 8.x. Personally I prefer to get e books in PDF. To much of a pain to try to read one page that references say a graph or table or illustration on another. Also found kindle sucks when you try to mag these last. Ordered "Bakers Dozen", but dumped the kindle version and got a refund from Amazon for these reasons.
Say what you will, knowing "of" the fundamentals is not the same as actually knowing "the" fundamentals. Fundamentals are essential, bottom line no matter how you slice it. Without them the momentum of the "spinning wheel" will eventually come to a stop and nobody will know how to re-start the wheel again. The mentality that the wheel will somehow just keep spinning is the downfall of many companies and for that matter on a much larger scale and longer cycle ... the downfall of entire civilizations. If history is to repeat itself, then abolishing fundamental concepts is a major contributor to the ultimate demise.
Now you got me. What's a more recent method than Quine-McCluskey? I might need it if I ever get around to building that CPU out of relays/transistors that I sometimes day dream about.
Probably nothing. I was just pointing out that both Karnaugh Maps and the Quine-McCluskey method date back to the same time period, the mid 1950's.

And nobody use BCD decoders anymore, but the stuff it teaches is good to know.
PM your email address and I lend it to you for 14days (yes kindle system let me do that, one person at a time)

Although they do not show up on the RS web search, I still find them available at the stores.
(I think I have them all from the 80's)

In a search for that question I discovered the Quine-McCluskey algorithm: http://en.wikipedia.org/wiki/Quine%E2%80%93McCluskey_algorithm
There are free implementations of it in various languages and you can try it out here: http://booleanbot.com/
Jack Crenshaw discusses it here: http://www.embedded.com/electronics-blogs/programmer-s-toolbox/4025004/All-about-Quine-McClusky
So this is great, this free book has indirectly taught me something entirely new. And I haven't had my morning coffee yet !
Twitter, smartphones, GPS, etc.
Note - "Mims" has two "m"s in it, not threee!
