How does a logic gate work?

How does a logic gate work?

When a transistor is on, or open, then an electric current can flow through. And when it’s off, then no current flows. When you string a bunch of these transistors together, then you get what’s called a logic gate, which lets you add, subtract, multiply, and divide binary numbers in any way imaginable.

Why are logic gates so important?

Logic gates are used to make decisions so that electrical outputs only ‘turn on’ when the correct logic sequence has been applied. Each logic gate has a name that helps to describe how different inputs will determine the possible outputs .

How is a logic gate created?

“A logic gate in a microchip is made up of a specific arrangement of transistors. For modern microchips, the transistors are of the kind called Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), and the semiconductor used is silicon. “In a logic-gate arrangement, each of the MOSFETs works like a switch.

Who invented the logic gates?

Walther Bothe, inventor of the coincidence circuit, got part of the 1954 Nobel Prize in physics, for the first modern electronic AND gate in 1924. Konrad Zuse designed and built electromechanical logic gates for his computer Z1 (from 1935 to 1938).

Where and logic gates are used in real life?

Applications of Logic Gates

• NAND Gates are used in Burglar alarms and buzzers.
• They are basically used in circuits involving computation and processing.
• They are also used in push button switches.
• They are used in the functioning of street lights.
• AND Gates are used to enable/inhibit the data transfer function.

How is logic gates used in real life?

Real-life applications of logic gates are: NAND gates used in burglar alarms and buzzers. They are also used in push button switches, and functioning of street lights. AND gates used to enable/inhibit the data transfer.
