### Why logic gates are called as logic gates not boolean gates?

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.

### What are the uses of logic gates in computing and communication technology?

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…

### Can logic gates have analog input?

It's an ambiguous question, because technically all signals are analog. The short answer is no. By asserting they are logic gates, you are supposing digital logic criteria and analysis: high impedance input, nominal output impedance, the transistor's operating regions are either saturation or cutoff, and the I/O signals are analyzed in discrete steady-states. Digital signals are applied to logic gates as the distinction of "digital" establishes the above signal criteria and circuit operation.

### 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…

### Is a transistors an analog device?

yes transistor is analog device because it can process the analog signal . But it can also used as digital devices as we know transistors are used for manufacturing logic gates and several digital devices as multiplexer and decoder encoder and memories also. it is the basic element of digital devices.

### What are the uses of logic gates?

Logic gates are in fact the building block of digital electronics; they are formed by the combination of transistors (either BJT or MOSFET) to realize some digital operations (like logical OR, AND, INVERT ). Every digital product, like computers, mobile, calculators even digital watches, contain logic gates. The use of logic gates in digital world can be understood better by the following example: the single bit full adder in digital electronics is a logic circuit…

### What is the importance of digital electronics in society?

Digital electronics involves logic 0 and logic 1. It involves the devices and circuits such as gates, flip-flops, latches etc. The basic idea of Digital electronics is mandatory for microprocessor & microcontroller and also for computer architecture. So, any application which involves microprocessor or a computer have digital electronics in it. It can be security applications, error correcting & error detecting , power saving circuits etc.

### What is the functions of cmos to the motherboard?

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.

### What do you mean by logic gates?

it's a little and basic integrated circuit that makes calculations regarding Boole's logic (true/false) they can make various operations instantly regarding as the type of logic gate based on the 2 inputs, giving the result as output. they can make the OR operand, And, Xor,Not and a combination of them (cheaper) Nor,Nand,XNor it's the base for digital computing.

### What is digital elctronics?

The implementation of two-valued logic using electronic logic gates such as and gates, or gates and flip-flops. In such circuits the logical values true and false are represented by two different voltages, e.g. 0V for false and +5V for true. Similarly, numbers are normally represented in binary using two different voltages to represented zero and one. Digital electronics contrasts with analogue electronics which represents continuously varying quantities like sound pressure using continuously varying voltages. Digital…

### Why NAND gates and NOR gates in logic circuits are universal gates?

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 ramendraawasthi@ymail.com They are called universal gates because all of the other gates…

### How do you construct other logic gates from nand gate?

NAND gates are universal gates and can be used to construct any of the logic gates (AND, OR, NOT, NOR, XOR, XNOR). The easiest way to figure this out is to use basic Boolean Laws. For instance, to create a NOT gate (A'), tie one of the NAND gate's input to logic high: (A+1)' = A'. To create an AND gate (AxB), use two NANDs in series, with the second one configured as an inverter…

### What is the difference between digital and analog computer's?

Analogue computers use varying voltages summed together to perform mathematical equations such as trajectories of artllery shells . Direct coupled dc operational amplifiers connected to summing resistors and dividers form the hardware gates of AND and OR. Inputs are set with ppotential dividers and outputs sent to analogue meters. They fell out of use in the 1960's when digital electronics became practical. Digital computer use binary digits using saturated logic. For example logic 1 is…

### Difrance between ic and ttl?

ic refers to integrated circuits and ttl refers to transistor transistor logic. ttl is a family which provides the basic or former structure of logic gates for example different logic gates such as NAND,NOR etc can be made out with the help of transistors connected in a specific manner. integerated circuits are the combination of logic gates presented on a base with equal number of input pins . for example IC-7408 contains 14 pins

### Name two logic gates?

The following are all common digital electronic logic gate types: AND OR NAND NOR XOR NOT There 'truth tables' and therefore their corresponding functions can be found on wikipedia under articles entitled with their respective names. NAND is a very common gate in commercial digital electronics as all other gates can be imitated by connected the correct number of NAND gates in the correct way. These can then be placed on one IC (Integrated Circuit)…

### NAND and NOR gates are called universal gates primarily because they?

A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates. In practice, this is advantageous since NAND and NOR gates are economical and easier to fabricate and are the basic gates used in all IC digital logic families. In fact, an AND gate is typically implemented as a NAND gate followed by an inverter not the other…
