Logic Gate

Logic Gate

A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels

Logic Gate

In electronics, a logic gate is an idealized or physical device implementing a Boolean function; that is, it performs a logical operation on one or more binary inputs and produces a single binary output.

What is a logic gate and how does it work?

In electronics, there's a logic gate that works in the same, contrary way and it's called a NOT gate or inverter. Unlike AND and OR gates, it has only one input and one output. The output is exactly the opposite of the input, so if the input is a 0, the output is a 1 and vice versa

Why do we use logic gates?

These logic gates are the building blocks of combination logic circuits. An example of a combination circuit is a decoder, which converts the binary code data present at its input into a number of different output lines, one at a time producing an equivalent decimal code at its output.

What is inside a logic gate?

Digital Logic Gates. A Digital Logic Gate is an electronic circuit which makes logical decisions based on the combination of digital signals present on its inputs. Digital logic gates may have more than one input, (A, B, C, etc.) but generally only have one digital output, (Q).
