The output of a logic gate is represented through which of the following?

The output of a logic gate is represented through voltage levels. In digital circuits, logic gates operate using binary signals, where each signal level corresponds to a specific logical value. Typically, a high voltage level (often near the supply voltage, such as 5V or 3.3V) represents a logical "1," while a low voltage level (close to 0V) represents a logical "0." This binary representation using voltage levels allows for the processing and manipulation of digital information effectively.

Other options, while relevant in different contexts, do not accurately describe how logic gates output their results. Power ratios pertain more to signal strength and power transfer and are not used as a direct representation of logic levels. Resistance values are more associated with current flow and circuit design and do not reflect the logical states produced by a gate. Frequency modulation, on the other hand, is a technique used in analog communications to encode information, which is unrelated to the discrete voltage levels that convey logic states in digital electronics.
