6. Make the logic diagram for the following problems
1. (A+B).C
2. (P.Q+R).S
3. (U+V).(W+X) using NAND gate only.
4. (S.T)+(H.P) using NOR gate only.

7. Identify the Boolean function and Boolean expression from the following
1. F(a,b,c) = (a+b’).c
2. F(r,s,t) = (r.s+t’)

8. Draw the truth tables of the following logic gates with example
(a) OR

(c) XOR
(d) NAND
(e) NOR

9. Make the Truth Table for the following problems
1. F(p,q,r) = (p+q’).r
2. F(a,b,c,d) = (a.b+c’).d’
