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 which perform the logical addition of two single bit binary numbers (a,b,cin) a and b are the the two binary number of single digit (either 1 or 0) and cin is the carry input . say for example a,b,cin= 1,1,1 gave an logical sum output of 1 and a carry of 1 , a,b,cin= 110 gave sum= 0 and carry of 1. Now this adder can be formed by the combination of many gate like by using NAND gates only. or by using XOR , AND ,OR gates and so on. So, in a nutshell, the adder which is of great importance in your computer processor and also in many more applications is basically built from the logic gates.

∙ 11y agoThe application of logic gates in a computer system is simply in getting input (feedback) from outside the computer itself. Consider driving your car... IF vehicle in drive AND accelerator is pushed, THEN go forward. The vehicle transmission and the gas pedal could both have sensors to provide the logic gate input of true or false. The output of the logic gate would drive the on/off switch of the motor or whatever else you wanted to control. Of course this is just a primitive example and can be quite complex depending on the number of input sensors and the desired behavior of the output. If you are designing a computer system that needs external input from sensors (whether from human interaction of because it is a control system needing to know about external situations) you will be using some sort of logic gate.

Suppose 2 pushbutton has to be pressed simultaneously to start a motor.Then we make AND logic by electrical wiring connection . This same thing can be made with electronic circuit also.
ANSWER: The Application deals with logic decision making to achieve a logical wanted result.

∙ 12y agoLogic 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 make any gate. Bharat Sabne bharat_sabne@Yahoo.com

∙ 8y agoThe advantage is that it does what it was designed to do that that that designed function is the one the engineer needed done.
Just the same as a properly selected screw does what it was designed to do and that designed function is adequate to hold the parts together as the engineer that selected the screw needed them held.
Or any other subpart of any larger system has the advantage of doing what it was designed to do as a subpart and does what is needed by the complete system.

Does a multiplexer use combinational or sequential circuits?
combinational circuit
How you will determine hazard in combinational circuit?
hazards in combinational and sequential circuits
Why is Boolean algebra used for combinational logic circuits?
Because it is a very efficient language for describing their operation as well as a tool to assist in design optimization (reducing the cost of the circuit when built).
Sequential circuits and its definition?
a sequential circuit is an interconnection of combinational circuit and storage elements.The storage elements is called flip-flop,store binary information that indicates the sequentiol circuit at that time.
Explain the major difference between combinatorial logic and sequential logic?
It was mentioned that there are two different ways to connect two or more electrical devices together in a circuit. They can be connected by means of series connections or by means of parallel connections. When all the devices in a circuit are connected by series connections, then the circuit is referred to as a series circuit. When all the devices in a circuit are connected by parallel connections, then the circuit is referred to as a parallel circuit. A third type of circuit involves the dual use of series and parallel connections in a circuit; such circuits are referred to as compound circuits or combination circuits. The circuit depicted at the right is an example of the use of both series and parallel connections within the same circuit. In this case, light bulbs A and B are connected by parallel connections and light bulbs C and D are connected by series connections. This is an example of a combination circuitBy EngineerMuhammad Zaheer Meer GMS

What is combinational circuits in computer architecture?
combinational circuit is depend only on inputs,like sequential circuits its not depend on previous outputs.
Similarities between combinational logic circuit and sequential logic circuit?
both combinational and sequential circuits have two inputs and outputs..!
How combinational and sequential circuits implemented in VHDL?

What is the difference between combinational alu and sequential alu?
There is one main difference between combinational ALU and sequential ALU. Combinational ALU depends only on present circuits, and sequential ALU depends on both the present and the past.
What are the use of And logic gate?
AND logic gate is used to obtain the product of two digits. It is used in various combinational and sequential circuits.
What is Combination logic circuit?
The combinational logic circuits are a type of logic circuits containing only logic gates (AND, OR, XOR, NOT, NAND, NOR) and its output only depends on the current input (do not have memory).
Distinguish between combinational logic and sequential logic?
A combinational circuit's output depends only on its current inputs. This means, it has a truth table. A sequential circuit's output depends on its previous inputs. This means, it's output will depend on which state it is.
What solenoids do to a logic combinational design?
