I don't know what this electronic circuit does

In summary: D could stand for "sum" because the output is the sum of the two inputs, and B could stand for "carry" because the output is the carry of the two inputs.

Member advised to use the formatting template for all homework help requests
I have a homework question that asks me to draw up a truth table for the attached circuit.

As you can see I did this (I think correctly). There is also an attached question asking what function the circuit serves - I am not sure what function this is

Any pointers appreciated.

Hi jackill. :welcome:

Why did you call one output "sum" and the other "carry"?

Oops - I originally thought this was a half adder but later figured that wasn't correct. I forgot to change the boxes before I uploaded the image.

LOL, I tried to cheat and use Google Images to match on the circuit posted. This was the return... o0)

I guess there is a difference between what this circuit does, and what you thought the circuit did.

Narrow down the image to just the circuit:
Circuit.JPG

Then search again :wink:

OK guys, the deadline is up and I couldn't figure it out using your hints :(

Really appreciate the efforts though and I will format my question better next time as per the forum rules.
