In-class discussion/activities 1st hour
MGF 093912: BINARY SYSTEMS INTRODUCTION. I didn't quite get through Moore's Law and discussion on the computing singularity, so I will start with that and use that to introduce binary systems. Briefly talk about transistors as switches, the equivalence of power on-off, 0-1, and T-F. I will then talk about three representations: Boolean algebra, truth tables, circuit diagrams. Then cover the fundamental logic gates (AND, OR, NOT), and then the common additional gates (NAND, NOR, XOR). Show the Boolean algebra for each of these, the truth tables, and gate for each. Finally if there is time I will pull up the Logic gate practice applet to demo it (using only 1 gate for today). Mostly a lecture and discussion day, no real student activities other than have those with laptops and tablets follow along with the practice applets.
Here is an excellent resource, I may add this in the notes section of Week #2 as a resource for students who wish to go much deeper into this: http://www.allaboutcircuits.com/vol_4/index.html
