1. What you know
2. What you have tried
3. The setting into which it is to be implemented
4. What constraits you have to adhere to

Thread moved from EE to Homework Help.

You must show us your work before we can offer tutorial help. Show us your ternary truth table for a full adder and for a full subtractor.
