A primer on Karnaugh maps

Simplification can actually reduce the number of logic gates you need. And Karnaugh maps are a good simplification tool. Last time, I introduced the ideas…

It’s only logical

From Aristotle to Boole, Jack traces a history of logic and then explains how to simplify Boolean equations. It's funny how sometimes when you're in…

I think I get it

Jack's spent over three decades working on his root finder. At long last, he finally understands why it ever worked in the first place. A…

Get More Yet

Jack's Rosetta Stone equation leads to some useful predictive techniques. Here's one based on difference tables. We've been talking about digital data processing, how to…

Getting It, Part Deux

From theory to practice in one easy lesson. Jack connects the digital and analog worlds with one simple equation. Just when you think you're doing…

On Getting It

Being digital, embedded systems “think” in discrete time, but they interact with a continuous-time world. Jack's got the key to bridging that gap. Tell a…
