Are you becoming a electronics engineer or something? Looks confusing to me.
A 4 bit full adder circuit :O My very first useful digital circuit.
The schematic is really messy, I didn't spend a lot of time making it neat, and it probably has a bit of mistakes when I translated the expressions over to the schematic.
Really, it shouldn't take longer than 30 minutes to design this, I just haven't done it before so o.o

There are two types of tragedies in life. One is not getting what you want, the other is getting it.
If you wake up at a different time in a different place, could you wake up as a different person?

what's the round line under the or gate?
Any type of engineering you do, you have to cover electricity stuff.

i think itz Boolean algebra and the structure seems like combination of AND, OR n NOR gates.
not sure though.

Its an XOR gate. Output is only high if one input and not the other is high.
I can just give you the expression for schematic I derived from the truth tables if you want (if that is what you are trying to get from the schematic) :S
CarryFlagOut = CarryFlagIn AND (Ax XOR Bx) OR (Ax AND Bx)
Outx = Ax XOR Bx XOR CarryFlagIn
I literally just repeat that logic for however many bits I want to add. Only because there is no carry for the first bit, I just use the same expression only with CarryFlagIn as zero and you get a simple XOR and AND gate.
Yeah, it is boolean algebra, but those are XOR gates not NOR gates. NOR gates look like plain OR gates but with a negation bubble at the output.
The next step is to put this into minecraft :O
Not sure about that. I doubt boolean algebra would be of any use to a civil engineer.
Yeah, atm I am studying Computer\Electrical Engineering.

I will pretend to understand this schematic, apparently drawn by an ingenious 5 year old, and applaud your efforts.
use a ruler man,
looks like some smart stuff.
I already did, in my previous response to Noob555's post. And it isn't that bad. I mean sure, the lines aren't straight, but you can deduce expressions from this. The gates are quite distinctive.
Designs for 4 bit full adders seem to be fairly consistent with each other, there really isn't much to explain other than to give the expressions I designed the circuit with.

Good job, theres some complex shit right there..
