nand gate
nand gate
When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
Not And (electronic logic gate)
NOR gate is equivalent to bubbled AND gate. -Nidhi Singh
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
A "Nand" gate is an "And" gate with an "Inverter" added to its output. To get a logic 1 output from a "Nand" gate, you need a logic 0 on both of its inputs. If I understand your question correctly, you have three "Nand" gates. Presumably the outputs of two of them are connected to the inputs of the third. Logic 1 at both inputs of the first two "Nand" gates will produce a logic 0 output from both of them. The two logic 0's are fed to the inputs of the third "Nand" gate producing a logic 0 output from the third "Nand" gate.
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
Nand 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.
NAND gate
1. NAND gate is used to invert the input A (by connecting A to both inputs). 2. NAND gate used to invert B the same way 3. Now put A' and B' into into a third NAND gate. The output will be (A'B')' which is equivalent to A+B.
