Question

If one input of an AND gate is considered to be an enable, it will enable the other input when it is ________?

1) High
2) Low
3) Undefined
4) None of the above

Answer 1

High

One input of an AND gate serves as an enable and will enable the other input when it is high. AND gates require both inputs to be high to output a high signal. Otherwise, the output will be low.

Step-by-step explanation:

If one input of an AND gate is considered to be an enable, it will enable the other input when it is high. AND gates are logic circuits that require both inputs to be high, or in a '1' state, to output a high signal.

Therefore, if one input is serving as an enable signal, it must be set high to allow the potential passage of the other input signal. Should the enable signal be low, or '0', the AND gate will output a low signal regardless of the state of the other input.

If one input of an AND gate is considered to be an enable, it will enable the other input when it is:

High

In digital logic, an AND gate produces a high output only when all of its inputs are high. If one input is considered to be an enable, it means that the AND gate will produce a high output only when both the enable input and the other input are high. Therefore, the enable input is expected to be high to enable the AND gate.
