Homework Help: Logic gates ?

  1. Mar 20, 2008 #1
    1. The problem statement, all variables and given/known data
    How can you inhibit NAND & NOT gate ? Mention whether the inhibit is active high or active low ?

    2. Relevant equations

    3. The attempt at a solution

    No clue to this question

    What does it mean to inhibit a gate?

    i myself don't know ? there are 16 boolean combinations for a 2 input gate & inhibit is one of them but i don't know more about it

    After some googling, the "inhibit gate" seems to be just an AND gate with one of the inputs called "the condition" or something like that. Perhaps the problem is asking you to build an AND gate from a NAND gate and from a NOR gate.

    "Inhibit" is not a term that most engineers would recognize. I suppose the question is asking "how do you disable a gate, so it's output remains constant."

    If you tie one input of an AND gate low, then it's output will always be low, no matter what happens on the other inputs.

    If you tie one input of an OR gate high, then it's output will always be high, no matter what happens on the other inputs.
