How many inputs does an AND logic gate require at a minimum?

An AND logic gate requires a minimum of two inputs to function. The fundamental operation of an AND gate is to output a true signal (often represented as a 1 or high signal) only when all of its inputs are true. With just one input, the gate could not logically perform an AND operation, as there would be no second input to compare against. Therefore, the design of the AND gate inherently specifies that it needs at least two inputs to implement its logic correctly. This capability allows it to process multiple signals and produce a singular output that reflects the logical conjunction of those signals.
