1. Explain NOR gate as Universal Gate A NOR gate is a simple OR gate with an inverter (NOT gate) at the output. NOR gates are considered Universal Gates because thay can be configured in a few different ways. Connecting the inputs on a NOR gate will result in a NOT gate (inverter). Connecting the above to the output of a NOR gate results in an OR gate.
Use 4 NOR gates. For the 1st NOR gate, inputs should be x' and y For the 2nd NOR gate,inputs should be y' and x The outputs of NOR 1 and NOR 2 are taken as inputs of NOR gate 3 The output of NOR 3 is the complemented form of the output required, so, just complement the output of NOR gate 3 with another NOR gate and Viola!, you have your HALF ADDER OUTPUT PS:I have used a double rail logic, where both x:x' and y:y' are available
This is made by joining the inputs of a NOR gate. As a NOR gate is equivalent to an OR gate leading to NOT gate, this automatically sees to the "OR" part of the NOR gate, eliminating it from consideration and leaving only the NOT part. Truth Table Input A Output Q 0 1 1 0
b'coz t mobility of electrons in NAND gate is 3 times higher than that of NOR gate
an 2 input AND gate can be realize using 3 NOR gates.Let ,A and B are the input and x be the output.x=A.B= NOR(NOR(A) NOR(B))
NOR gate is equivalent to bubbled AND gate. -Nidhi Singh

Yes._____A----|_____NOR------QThis is an inverter. A NOR gate is an OR gate with an inverter on the end, so adding the above configuration after another NOR gate would give you an OR gate.__A----|__NOR---\__ NOR------QB----|__NOR---/This is an AND gate. By adding the inverter, you can get a NAND gate.A____|___|__NOR----------------\| | \| |___ NOR----QB __| |___NOR-----\ /|_____ NOR --/|_____NOR-----/By combining an AND gate, an OR gate, and a NAND gate, and canceling out a couple of inverters, you get this operator, which is a XOR gate.The formatting here is messed up, but if you go to the "improve answer" link, you can see the circuits.
A 2 input NAND gate requires 4 NOR gates.A 3 input NAND gate requires 5 NOR gates.A 4 input NAND gate requires 6 NOR gates.etc.
nor to and
In grammar, it is a negative "or", as in "It is neither fish nor fowl" In logic circuitry, it is a "not or" gate, which is the inverse of an "or" gate
A nor gate provides an output of 0 when any input is 1.Nor gate provides the opposite of or gate. An or gate provides a 1 or true output when any of the inputs is 1 or true. Therefore the opposite output would be provided by a nor gate.
