## 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 LOGIC FUNCTION SIMULATOR?

Logic function simulator,

• Draws the circuit of an entered Boolean function,
• Shows the output of each logic gate in the circuit and
• Allows to change the variable values.

To change the value of a variable, you can click on the variable name that appaers above the circuit.

### HOW TO USE THE LOGIC FUNCTION SIMULATOR?

You can use the logic function simulator in two ways.

• #### USER INPUTS

You can enter a Boolean expression to the input box and click on the "SIMULATE" 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 simulate some other Boolean functions you can clear the input box by clicking on the CLEAR button under the input box.

• You can copy the generated solution by clicking on the "Copy Text" link, appaers under the solution panel.

• Even you can download the solution as an image file with .jpg extension if you click on the "Download Solution" link at the bottom of the solution panel. You can share the downloaded image file.
