Question

A mother wants you to design a logic circuit to let her child know whether a snack is appropriate, based on his selection of Apple juice (abbreviated A), Bubble gum (abbreviated B), and a Cup (abbreviated C) Her requirements are as follows: There are exactly two cases where the output (Good) must be false: If the child selects bubble gum, or If the child selects apple juice but no cup o o In all other cases, the output should be true. Yes, this means the child could select nothing for a snack, or just a cup. At least he won't spill apple juice everywhere. Tip: Since you are given all the cases where the output must be false, you can come up with an expression for G (i.e. where the expression is false) and then invert both sides to get an expression for G. You should this leave the expression as-is, with a bar over the entire right side. You can also solve the truth table for a minimal SoP expression, but then you will want to simplify it algebraically. a) Write a Boolean expression for G in terms of A, B, and C.
