Logiikkalaitteiden, or logic gates in English, are fundamental building blocks of digital circuits. They are electronic devices that perform a basic logical operation on one or more binary inputs and produce a single binary output. The output is determined by the combination of the input values according to a specific logical function. Common logic gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR.

An AND gate outputs a high signal (1) only if all its inputs are high. An OR gate outputs a high signal if at least one of its inputs is high. A NOT gate, also known as an inverter, has a single input and outputs the opposite of its input; if the input is high, the output is low, and vice versa. NAND (NOT-AND) and NOR (NOT-OR) gates are the negations of AND and OR gates, respectively, meaning they output low only when the corresponding AND or OR gate would output high. XOR (exclusive OR) outputs high if the inputs are different, and XNOR (exclusive NOR) outputs high if the inputs are the same.

These simple gates can be combined in numerous ways to create more complex digital circuits, such as adders, multiplexers, flip-flops, and ultimately, microprocessors. The operation of logic gates is based on the principles of Boolean algebra. They are essential components in virtually all digital systems, from simple calculators to sophisticated computers and smartphones. Understanding logic gates is crucial for anyone studying digital electronics, computer engineering, or computer science.
