1. i want to design a 2 bit full adder (that adds two numbers each having 2 bits) with carry in and carry out and to show the output on seven segment display..




3. the problem is that i am student in mechanical power and i am taking an electronics course..can you tell me what to do or some hints please..

You can get a 4-bit full adder as an IC:

We don't give out answers to homework here on the PF. We can offer tutorial help if you show us your work. Read this about full adders:

http://en.wikipedia.org/wiki/Full_adder#Full_adder

And this about 7-segment displays:

Then sketch up your initial thoughts, and ask us specific questions about your circuit if you have any.

what is the common cathode (3,8) ? does it means that these two pins (3,8) must be connected to the ground ?
