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.

How do you design a half-adder using NOR 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
Any logical function can be implemented with only NOR gates?
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.
Why is nand gate prefer over nor gate?
The nand gate is prefered over the nor gate because for a nand gate, all other states are true except the 1 1 state which is false while for a nor gate all other states are false except the 0 0 state which is true.
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
Is there any similarity between NA ND gate and NOR gate in digital logic?
no
