a. (a+b+c’)(a’b’+c)
b. x’y’z’ + w’x’yz’ + wx’yz’
2. A)Find complement of F=(a+c)(a+b’)(a’+b+c’)
and produce a truth table F’. (10 marks)
B) Find the complement for F using the Dual
Principle (5marks)

b. F= ac’b+c’+d’b’
4. From the table produce the function expression as
sum of products ,i.e. f(xyz)=…+..+…, Simplify the
expression algebraically and draw the circuit for the
simplified expression. (15 marks)
