In a NOR gate configuration, if input A goes low and input L goes high, what will be the output?

• A. High
• B. Low
• C. Undefined
• D. Stable

Answer: (B)

In a NOR gate, the output is true only when both inputs are false (low). The logical operation of a NOR gate can be expressed as follows: the output will be low if one or both of the inputs are high. In the given scenario, when input A goes low, it represents a false condition. However, with input L going high, this indicates a true condition. Since one of the inputs (L) is high, the output cannot be high. Instead, the output of the NOR gate will be low because the presence of a high input negates the condition for the output to be high. Thus, when one input is low and the other is high, the output is determined by the logic of the NOR gate, which results in a low output.
