## TOOL: XNOR GATE LEARNING TOOL

#### XNOR GATE LEARNING TOOL

Click on an input or a row on the truth table to change the input values.

F = xy

= 10

= 0

## INFORMATION

An XNOR gate may have 2 or more inputs. The logic value at the output depends on the algebraic sum of the values at the inputs. If the sum is an even number, the output is logic-1. Otherwise, the output is logic-0.

The truth table for a two-input XNOR gate is as follows:

In this table, x and y represent the inputs and F represents the output. Each row in the table indicates the corresponding output value based on the values of inputs in that row. For example, the first row indicates that F = 0 for x = 0 and y = 0.

In logic, the XNOR operation is represented by the "⊙" symbol. For example, the expression "A ⊙ B" means "A xnor B".

### WHAT IS XNOR GATE LEARNING TOOL?

XNOR gate learning tool,

• Allows the user to select the input values for a 2-input, 3-input or 4-input XNOR gate,
• Illustrates the output on the circuit symbol and the truth table.

### HOW TO USE THE XNOR GATE LEARNING TOOL?

You can select the input values yourself or set them randomly.

• #### USER INPUTS

To toggle the input values between 1 and 0, click on the inputs.

Or click on any row on the truth table to set the input values.

ALL = 0 and ALL = 1 buttons reset and set all input values, respectively.

• #### RANDOM INPUTS

The DIE ICON generates a random set of values for the inputs.

• #### SELECTING THE NUMBER OF INPUTS

2, 3, and 4 input XNOR gates are available.
