This is a NOT-AND gate, that is an AND gate followed by a NOT gate. It acts in the manner of the logical operation "and" followed by negation. The outputs of all NAND gates are high if any of the inputs are low. The symbol is an AND gate with a small circle on the output. The small circle represents inversion.
A NAND GATE with 3 input
The NOR gate
The NOR gate is a combination OR gate followed by an inverter. That is a NOT-OR gate is equal to an OR gate followed by a NOT gate. The symbol is an OR gate with a small circle on the output. The small circle represents inversion. Its output is "true" if all inputs are "false." Otherwise, the output is "false."
the Nand and Nor gates are just the inverse of the And and Or gates.. we have to memorise only the AND or OR gates and we can easily inverse them...sooo easy..thx Mrs. Jannoo for this incredible platform for us to meet n post comments
ReplyDeleteyes vimalen u r rite... we just have to remember the basic gates to complete these nand and nor gates
ReplyDeletethis chapter is exciting n we never get bored...though sometimes i tend to confuse among the gates
