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.
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
AND gate is an all or nothing gate because in able to have an output of logic 1,all of the input must be all logic 1 or else the output will be nothing or simply logic 0.
If the output of a logic gate is 1 while all inputs are logic 0, the gate is a NOR gate. A NOR gate produces a high output (1) only when all its inputs are low (0). In contrast, other gates like AND, OR, and NAND would not produce a 1 output under these conditions.
NAND gate
It becomes an or gate or, possibly, an and gate, depending on how you look at it..
An AND gate is a logic gate performing a Boolean logic AND operation.
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
When the two input terminals of a NAND gate are short circuited, it acts as a NOT gate.
An XNOR gate is a logic gate performing a Boolean logic XNOR operation, also known as an equivalence gate.
The switching time (on and off) of the TTL logic gate is very fast in comparison with CMOS logic gate. However, they could not tolerate higher range of power supply.
AND gate is an all or nothing gate because in able to have an output of logic 1,all of the input must be all logic 1 or else the output will be nothing or simply logic 0.
All the inputs of the gate must be set to a logic 1 for the gate to open.
Any logic gate from which all other logic gate functions can be derived. The two universal gates are NAND and NOR.
AOI logic stands for AND OR INVERT logic. AND gate in this logic is formed by two PMOS and two NMOS FETs. Its function is to AND two bits.
Exclusive OR
AND
because some of the logic gate are opened in 0volt
