## 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".

### WHAT IS DUAL OF A FUNCTION CALCULATOR?

Dual of a function calculator,

• Finds the dual of an entered Boolean function.

### 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.
