# What Is Combinational Circuit Explain With Example

By | July 27, 2022

Combinational circuits are powerful devices that can be used to create digital electronics, robotics, and more. They combine a set of inputs to produce a resulting output. In essence, combinational circuits are at the heart of many modern electronic devices.

A combinational circuit uses Boolean logic to determine the output based on the combination of inputs. Depending on the type of circuit, the output may be a continuous value or a digital signal. The advantage of combinational circuits is the speed with which they can process data. They are also well suited for applications where the same output is required regardless of the order in which the inputs are presented.

Let's look at a simple example of a combinational circuit. Imagine a flagpole with two lights, one red and one green. When both lights are lit up, it signifies that it is safe to enter the building. This circuit is an example of a combinational circuit because it takes two inputs (the red and green lights) and produces an output (either safe or not safe).

More complex examples of combinational circuits can be found in computers and mobile phones. For example, a mobile phone might have a processor, memory, and display all connected together by a combinational circuit. Each component operates its own logic, and the circuit ties them together. This allows the user to access different programs and apps, send messages, make calls, and surf the web.

Combinational circuits can also be used for control systems in robotics. By connecting various sensors to the robotic system, the robot can be programmed to react to these inputs and make decisions to control the robot. The input could be from a proximity sensor or from a camera or from any other sensor. By combining these inputs, the robot can be programmed to take evasive action when needed, or to interact with its environment.

In conclusion, combinational circuits are extremely versatile devices that can be used in a variety of contexts. From safety lights to mobile phones to robotics, combinational circuits are found in many parts of everyday life. By combining a set of inputs and applying Boolean logic to them, combinational circuits can output a desired result, bringing efficiency and precision to a variety of tasks.
