two nand gates
by multiplying two NAND gates
As such an OR gate should do the job...but if the question is of using gates other than the simple OR, it should be a combo of NOR and NOT gates; where-in, the NOT gate comes after the NOR gate. Factfully speaking: The output of a NOR gate when fed to a NOT gate shall give you an OR gate. cheers :) Anish Murthy Airpula, RF Design Engineer (F.A.E) Ceramic & Microwave Products Group, Dover Corporation Inc, United States of America
1 gate.
A 2 input NAND gate requires 4 NOR gates.A 3 input NAND gate requires 5 NOR gates.A 4 input NAND gate requires 6 NOR gates.etc.
for a two input gate to represent as an n-input gate excatly n-1 two input gates are required. this implies that for a two input OR gate to represent a four input OR gate exactly three two input OR gates are required let F is =a+b+c+d =(((a+b)+c)+d) =((a+b)+(c+d)) in both the above cases + is used three times so three two input OR gates make a four input OR gates. This discussion doesnot hold good for NAND gates an example can illlustrate the reson:- take F=(a.b.c.d)'=a'+b'+c'+d' --------------------------->(1) (this is obtained by a four input NAND gate) let us take this in the manner we did it for an OR gate and we will then verify the result. =((a.b)'(c.d)')' =((a'+b').(c'+d'))' =(a'+b')'+(c'+d')' =ab+cd <------------------------(2) (1)is not equal to (2) so we can say that a NAND gate cannot be replaced in the manner as OR gate is replaced
Bill Gates has one son, Rory John Gates born in 1999.
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.
in generlly , how many ping of ic that we can use in over basec gate ?
Short answer: we don't know. Most of our information pertains to the Second Temple rather than to the First.The Talmud (Mishna, Middoth ch.1) lists the gates in the Second Temple:A) The five gates of the Temple Mount:the two Huldah gates to the souththe Kiponos gate to the westthe Tadi gate to the norththe Shushan gate to the eastB) The seven gates of the Temple courtyard:the kindling-gate to the souththe sacrifice-gate to the souththe water-gate to the souththe gate of Nicanor to the eastthe gate of the flame ("spark") to the norththe sacrifice-gate to the norththe gate of the hearth-chamber to the northNote that within the Temple complex there were many structures, so that there were entranceways besides those listed here.

Rock Lee can open Six chakra gates. Rock Lee is not capable of opening all chakra gates. When Rock Lee was fighting Gaara, Kakashi asked Might Guy how many gates he had got up to. Guy said he was up to five gates. Now that he has trained during time-skip, Rock Lee can probably open the sixth chakra gate now.
There are many different types of gates automation. The most common is a swing gate and these can be controlled by Linear arms, these are placed on the gate post and also on the the gates themselves and the motor will pull the gate open. Its the same principle when shutting the gate the motor will push the gate closed. Other types are underground motors, these are buried in the ground under the gates hinge and the load bearing box will act as the bottom hinge for the gate. This motor will twist the bottom of the gate making the gate open and close. You can also get sliding gate operators the have a cog and a toothed track will sit on this cog and once the motor tuns the cog the sliding gate will move either to open or close.
