## TOOL: OR GATE LEARNING TOOL

#### OR GATE LEARNING TOOL

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

F = x + y

= 1 + 0

= 1

## INFORMATION

The OR gate is one of the fundamental gates used in logic systems. An OR gate can have 2 or more inputs. The logic value at the output depends on the values at the inputs. When all inputs are logic-0, the output is also logic-0. In all other cases, the output is logic-1. In other words, the output of an OR gate is logic-1 if at least one of the inputs is logic-1.

The truth table for a two-input OR 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 OR operation is represented by the "∨" or "+" symbol. For example, the expression "A + B" means "A or B".

### WHAT IS OR GATE LEARNING TOOL?

OR gate learning tool,

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

### HOW TO USE THE OR 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 OR gates are available.
