Question

Logic gate is a digital circuit with ___________ .

Answer 1

Hint: It is a device that serves as a foundation for digital circuits. They carry out basic logical operations that are essential in digital circuitry. Logic gates are found in almost every technological equipment we use today.

Complete answer:
Logic gate is a digital circuit with one or more inputs and a single output.
A logic gate is an idealistic model of computing or a practical electronic device that implements a Boolean function, which is a logical operation that creates a single binary output from one or more binary inputs. The word may refer to an ideal logic gate, such as one with zero rise time and unbounded fan-out, or it may refer to a non-perfect physical device, depending on the context (see Ideal and real op-amps for comparison).
Diodes or transistors operate as electronic switches in logic gates, but they can also be built with vacuum tubes, electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical parts. Amplification allows the building of a physical model of all Boolean logic, and thus all of the algorithms and mathematics that can be expressed with Boolean logic, in the same manner that Boolean functions may be built.
There are three types of logic gates:-
$*$ AND Gate
$*$ OR Gate
$*$ NOT Gate

Note:
Combining logic gates, we can make universal gates. NAND and NOR gates are called universal gates because they can be combined to produce any of the other gates like OR, AND, and NOT gates. Universal gates are widely utilised because they are simple to construct and cost-effective.
