Mar 03, 2010 · Give the boolean expression from the above circuit diagram. 5. A truth table has the same states as in number 3 above. However, the output column from top to bottom reads 00110101. Give the result of the sum of products method. 6. Give the result of the product of sums method in number 5 above. 7. A boolean expression is given Y = (A+B)C+!BA+!C ... Expressions • Up to now we have seen • arithmetic expressions that use the operators + - * / % ++ --• assignment expressions that use the operators = += -= … • Boolean expressions use relational and logical operators. • The result of a Boolean expression is either true or false. • Boolean expressions allow us to write programs that schematic representation. By starting with a list of inputs to the circuit, then passing each input through the correct gates, we can develop the circuit. Figure 5-9 does just this for the previous boolean expression. We list the inputs for the expression, A, B, C, and D, on the left side of the figure.
