INFORMATION

To find the dual of a Boolean function, follow the steps below.

• Replace each variable with its complement (change every '0' to '1' and every '1' to '0').
• Replace AND operations with OR operations.
• Replace OR operations with AND operations.

INPUT FORMAT

VARIABLES: Use letters such as A, B, C, x, y, z to represent the variables.

COMPLEMENT: To denote the complement of a variable or term, use the ' symbol to the right. For example, x' means "complement of x"; (x + y)' means "complement of x + y".

AND: There are three alternatives for representing the AND operation. You can use either the . or * symbol between variables. Furthermore, placing variables next to each other implies they are being ANDed. For instance, x.y, x*y, and xy all signify "x AND y".

OR: For OR operation use + symbol. For example, x + y means "x OR y".

HOW TO USE THE DUAL OF A FUNCTION CALCULATOR?

You can use the dual of function calculator in two ways.

• USER INPUTS

  

  You can enter a Boolean expression to the input box and click on the "DUAL" button. The result and explanations appaer below the calculator.

• RANDOM INPUTS

  

  You can click on the DIE ICON next to the input box. If you use this property, a random Boolean function is generated and entered to the calculator, automatically. You can see the result and explanations below the calculator. You can create your own examples and practice using this property.

• CLEARING THE INPUT BOX

  

  To find the dual of some other Boolean functions you can clear the input box by clicking on the CLEAR button under the input box.
