7. Show that the following two gate circuits realize the same function DD- 8. For each of the following Boolean expression, obtain its standard form as product of sum. (a) K' L' M + KM' N+KLM+LM' N' (four terms) (b) KL + K' L' +' M' N' +LMN' (four terms) (c) KL +K'L' M+L' M' N+LM' N' (four terms) (d) K' M' N + KL' N' +K' MN' +LN (four terms) (e) WXY+WX Y + WYZ + XYZ (three terms) Then obtain its canonical form in product of maxterms (either algebraically or using truth table) 9. For each of the following Boolean expression, obtain its standard form as sum of products. (a) (K +M' +NXK' + MXL+M' +N K +L + MXM+N) (three terms) (b) (K" +L + M' MK + M +N' MK-L0K + NK + M + N) (c) (K" + L + M K +N MK" +L+N K+ LyK+M+N" ) (d) (K+L+M)(K' +'+ N K +L +M K+L+N) (e) (K+L+M K+M+NXK' L' M' K' +M' +N' ) Then obtain its canonical form in sum of minterms (either algebraically or using truth table)
