In logic circuits, when will the output be LOW?

In logic circuits, the output being LOW is typically determined by the configuration of the logic gates being used. For many basic logic gates, especially the AND gate, the output will be LOW when all inputs are LOW. This is because the AND gate requires all its inputs to be HIGH to produce a HIGH output; any LOW input results in a LOW output.

When the question states "when all inputs are low," it effectively refers to this essential operational characteristic. In this scenario, the circuit logic signifies that zero voltage or a binary '0' is represented at the output, confirming the LOW state.

In contrast, if even one input is HIGH while the others may be LOW or if multiple inputs are HIGH, the output may not be LOW. Specifically:

• If there's at least one HIGH input, the result could be HIGH depending on the gate's design.

• If some inputs are LOW, that doesn't guarantee a LOW output unless the defined parameters for the circuit specify such.

Thus, the understanding of this output behavior is crucial for anyone working with digital logic to predict the overall function of the circuit correctly.
