Why logic gates are called logic gates?
Logic Gates are electronic building blocks of a digital system.
Their physical manifestation may take any form, but essentially a logic gate consists of a collection of binary digits and a set of rules where such digits are combined to give a resulting set of binary digits.
The rules that are implemented by logic gate are of the fundamental Boolean Algebraic Operations.
Logic gates may be coupled together so that digital input to a system produces a predetermined digital output. It is a logical set of rules. The concept of digital information flowing into a system through an electronic pathway coveys a perception that gave someone the idea of a gate when this was named long ago.
Logic gates are the basic building blocks of digital circuits or systems. these digital circuits are used to implement several combinational and sequential operations. these operations include starage, timing, arithmetic, coding, communication etc. Hence, implementing the boolean algebra is not the only purpose where logic gates are used, hence, it is opt to call them as logic gates rather than boolean gates.
THE MAIN ADVANTAGE OF THE UNIVERSAL LOGIC GATES IS THAT IT CAN BE USED TO MADE ANT KIND OF LOGIC GATE .......BY USING IT . NAND AND NOR ARE CALLED AS UNIVERSAL GATES ARE USED TO MAKE ANY GAATES AS OR ,AND, XNOR,NOT. logic gates are used in many everyday electronic devices such as tv's, computers and telephones.
NAND AND NOR gates are called universal gates , becaus with a combination NAND and NOR gates alone, it's possible to create all other logic gates like AND, OR, XOR etc and you can design any logic circuit. eg: inverter-- nand with inputs shorted. and ------ nand followed by a inverter(using nand). or--------- giving inverted inputs to nand gate.
Logic gates is used in digital techenology, computer is a digital mechine. digital means 0 1, here 0 is off & 1 is on. from this logic make a logic gates there are three basic logic gates 1) AND gate 2)OR gate 3) NOT gate using those gates we can made another gates AND + Not NAND gate OR + NOT NOR gate theose two gates are univarsal gares because using those two gate you…
Because they are based on physical semi-conductor devices, called gates. Also look at it this way. The flow of electrons of your circuit is directed and controlled by the logical operations that the circuit designer wanted them to follow. Then the devices that control the flow of electrons are called gates. What kind of gates? logic, digital gates operating with low voltages: 0 (no difference in potential) and 1 (voltage applied). Look at it the…
CMOS (complementary metal oxide semi conductor) is a logic family. A logic family refers to the way of implementing logic. Using this technique, logic gates are realized. The combination of several logic gates forms a digital circuit or integrated circuit (IC). A mother board is also an IC. The technique used to realize it is CMOS logic.
actually any digital circuit can be designed by using only any one type of gates either nand or nor that's why they are called as universal gate. even basic logic gates AND ,OR,NOT can also be designed using them.now choosing one of two (nor n nand) depends on if logic expression is of sop type or pos type. by-ramendra for more info contact firstname.lastname@example.org They are called universal gates because all of the other gates…
