Second Soliloquy

A journey into the mindscape...

7-Segment Decoders, Truth Tables, and K-Maps

I missed an assignment worth 80 points for Advanced Electronics. The people who passed theirs already got them back, checked. That means I can't pass the assignment anymore because the answers are all out. Now, just so I don't miss out on so many points, I have an alternative worth only 64 points. Out of the 17 topics we're eventually going to cover in the first quarter, I either get two from 1-12 or one from 13-17, and research/explain/compute them. I chose #13, the 7-segment decoder.

The 7-segment decoder recieves a 4 bit input and outputs to a 7-segment display representing the hexadecimal value of the input from 0-F. My job is to derive the schematic diagram for each segment (a through g). Now imagine setting up a truth table for 4 variables with 7 outputs, constructing 7 Karnaugh maps (K-maps), eventually coming up with 7 sum-of-product boolean expressions. I still have to simplify these expressions, then make an equivlent schematic diagram for all of them.

Seems like a complicated lot, doesn't it? Well, it seems this is the consequence of the choices I make. Perhaps I could lean from this experience?
