What is a four input and gate?
A four input and gate is a logic gate with four inputs. The output is true only when all four inputs are true.
What Gate that always inverts its single input as an output?
"not" gate
How exclusive or gate is converted in not gate?
one terminal of the ex-or gate should be connected to a high input(1 or 5V). the other terminal is used as the input terminal,since not gate has only one input.when we give a high to this input, now the inputs of exor gate are 1 & 1.so output is 0.when we give a low to the input , then the inputs of ex-or gate are 0 and 1, output is 1. Hence it works as a controlled inverter.
How many two input NAND gates are required to implement a four input NAND gates?
NOR gate = not(A or B) = A nor BAND gate = A and BAND gate = not(not A or not B)AND gate = not(not(A or A) or not(B or B))AND gate = (A nor A) nor (B nor B)Therefore using 2 input NORs to make a 2 input AND you need three NORs. If you wanted something different (e.g. a 5 input AND) the above proof can be modified appropriately to get your answer.
