1)Expression to Circuit/Boolean Circuit to Expression: 2 + 2 +2+2=8 marks ( 4 questions)
2) Writing SOP & POS Expression (3 variables): 1+1+1+1 = 4 marks (4 questions)
3) Boolean Laws verification (truth table /Laws): 2 + 2+2+2 =8 marks ( 4 questions( any 4 laws) )
4) K-Map SOP & POS simplifying expression: 3 + 3 +3 + 3= 12 marks (2 SOP problems and 2 POS problems)
5) Additional gates symbol and truth table of 2 variables - 3 marks (any three)
