In logic gates, what does the "off" state indicate?

In logic gates, the "off" state typically indicates that the voltage is at zero. This is representative of a low signal or logical false state in digital circuits. When a gate is in the off state, it means that it does not conduct electricity and the output will not produce any high signal; instead, it remains at ground level (zero volts). This concept is fundamental in digital electronics where the two states—on (high voltage) and off (low voltage)—correspond to the binary values of 1 and 0, respectively. Therefore, understanding that the off state corresponds to zero voltage is crucial for analyzing how digital circuits operate.
