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: (AxB) = ((AxB)')'

Why NOR gate is called universal gate?
That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.
What is an AND gate?
An AND gate is a logic gate performing a Boolean logic AND operation.
What are some uses for logic gates in everyday life?
simply , it is used to control the circuit , for example if i have a lamp ( or LED) and i want to control when it should be on i used sequential logic gate ( or flip-flop ) with an exact input ( say '11' ) . ANSWER: There are no sequential logic gates. But there decoders and multiplexers whereby an output can occurs only when reaching a code or an address
What is the difference between sampling gates and logic gates?
A logic gate is a computer circuit with several inputs but only one output that can be activated by a particular combinations of inputs, a diagram that shows the major gates can be found here.An example would be if you have 2 wires going to an AND gate and only 1 wire has a current (is on, 1) and the other one is 0, then your output would be 0 as you need wire 1 AND wire 2 to have a current, for the output to be 1, on.A sampling gate, on the other hand is a circuit that produces an output only when first activated by a preliminary pulse. So if you have a current going through a wire and through a sampling gate, your output would be 0, unless you program the sampling gate to let the current through.I'm sorry if this is a slightly plain answer, but if you would like more reading, then go to the Wikipedia.
Device a circuit to perform OR logic using only NOR gate?
Use two NOR gates. Tie the output of the first to both (or all) inputs of the second. A logic one at any input of the first produces a logic one at the output of the second which is a standard OR.
What is universal logic gate?
universal logic gate is a gate using which you can make all the logic gates there are two such gates NOR gate and NAND gate
What is universal gates?
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
Why some of the logic circuit required another gates to construct the operation?
Because not all the logic gate have what the circuit needs to complete the operation
What is the definition of universal gate?
universal gates are the ones from which we can design other gates also. for eg. NAND and NOR gates. they help in forming the uniformity in the circuits.
What are the advantages of nand gate?
because it is an universal gate that control and repairs other gates.
Symbol of universal gate?
The two categories for logic gates are basic logic gates and universal gates. Gates are identified by their function and universal gates are identified as NAND gate or NOR gate.
Define universal gate?
A universal gate is a logic gate that can be used to implement any logic function. The NAND gate and NOR gate are examples of universal gates because any other logic gate can be constructed using only NAND or only NOR gates.
What are the diode logic gate?
A logic gate composed only of diodes and resistors. The only types are AND gates and OR gates. However the number of layers of logic that can be implemented are severely limited due to losses in these gates.
Why NOR gate is called universal gate?
That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.
What are the disadvantages of logic gates?
advantages for and gate
How nand gate acts as a universal gate?
A universal gate is a gate which can implement any Boolean function without need touse any other gate type.The NAND and NOR gates are universal gates.In practice, this is advantageous since NAND and NOR gates are economical andeasier 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 aninverter not the other way around!!Likewise, an OR gate is typically implemented as a NOR gate followed by an inverternot the other way around!!A universal gate is a gate which can implement any Boolean function without need touse any other gate type.The NAND and NOR gates are universal gates.In practice, this is advantageous since NAND and NOR gates are economical andeasier 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 aninverter not the other way around!!Likewise, an OR gate is typically implemented as a NOR gate followed by an inverternot the other way around!!can be combined to produce AND, OR,NOT,XORand XNOR gates
What logic gates have no unique outputs?
One gate would be the NOT gate.
