1) Which Boolean law is used to transform each of the following equations?
a. B + (D + E) = (B + D) + E
b. CAB=ABC
c. (B + C)(A + D)= BA + BD + CA + CD
d. D + E = E + D
2) Using Boolean algebra techniques, simplify this expression:
AB + A(B + C) + B(B + C)
3) Write the Boolean expression for each of the logic circuits below.
4) Draw a logic circuit for circuit represented by each expression:
a. AB' + A'B
b. AB + A'B: + A'BC
c. A'B(C + D')
d. A + B[C + D(B + C')]
5) Construct a truth table for each of the following Boolean expressions:
a. A + B
b. AB
c. AB + BC
d. (A + B)C
e. (A + B)(B' + C)
