A combinational circuit has three inputs A, B and C and an output F. F is true only for the following input combinations?
A is false and B is true
A is false and C is true
A, B and C are all false
A, B and C are all true.
(a)Write the truth table for F. use the convention, true = 1 and false = 0.
(b)Write the simplified expression for F as a Sum of Products.
(c) Write the simplified expression for F as a product of Sums.
(d) Draw a logic circuit implementation of F using the minimum number of 2
input NAND gates only.
