The teach already expl in class Here is the format:

                                           Page 1:
                                                              Dont write whatever is in the bracket............

Digital systems Lab Ex:2

The following expressions have to be proved using the truth table as well as logic gates.
Solve the exp. algebraically followed by the Truth Table. The logic gate diagram should be on the left page.

1. (AB+C'D)(AB+CD') = AB
2. ABCD+A'BD+ABC'D+A'D = D(A'+B)
3. A'C'+ABC+AC'+AB' = C'+AC
4. (X+XY)(X'+Y)+YZ = Y(X+Z)
5. ABC+A'B+ABC'+AC = B+AC
6. XY+X(WZ+WZ')

De Morgans Law:
1. (A+B)' = A'B'
2. (AB)' = A'+B'

Ill Post this as soon i get it......
