In this section, we’ll explain how Boolean logic became the foundation of digital circuits. There are logic gates in circuits, which are devices that serve as building blocks.
They’re in charge of performing logical functions in digital circuits such as those found in tablets, phones, and memory devices.
These logic gates make decisions based on the signals that they receive from their inputs. Most logic gates have two inputs and one output.
Since logic gates are based on Boolean logic, their terminals are one of two binary conditions. These conditions are either true, denoted by a 1, or false, denoted by a 0.
The binary output is determined by the logic circuit used as well as the combination of inputs. Consider the logic gate to be a light switch, where an input gives signals to turn off in the form of 0 and signals to turn on in the form of 1.
You may be wondering by now, what's the role of "AND," "OR," and "NOT" in such circuits? Actually, the logic gates are created using these operators.
"AND" Gate
Similar to what has been explained above, both input conditions must match in order to produce the desired output. This means that if both inputs are true, the output will be true. If one of the inputs is false, the output is also false.
"OR" Gate
The output of the "OR" gate is true if both or one of the inputs is true. As a result, if one input is true and the other is false, the output will be true.
"NOT" Gate
The "NOT" gate is referred to as a logic inverter. This gate only accepts one input and reverses its logic state. If the input is false, the output will be true. Similarly, if the input is true, the output will be false.
