Logiikkalaitteistot, also known as logic gates or digital logic circuits, are fundamental building blocks in digital electronics. They are electronic circuits that perform basic logical operations on one or more binary inputs and produce a single binary output. The output is determined by a specific logical function of the inputs. The most common types of logic gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR gates.

An AND gate outputs a high signal 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, outputs the opposite of its input; if the input is high, the output is low, and vice versa. NAND gates are the inverse of AND gates, and NOR gates are the inverse of OR gates. XOR (exclusive OR) gates output a high signal if an odd number of inputs are high. XNOR gates are the inverse of XOR gates.

These basic gates can be combined in various ways to create more complex digital circuits, such as adders, multiplexers, flip-flops, and microprocessors. They are essential for performing calculations, storing data, and controlling the flow of information in digital systems. The design and implementation of logic circuits rely on Boolean algebra, which provides a mathematical framework for analyzing and simplifying logical operations. Integrated circuits (ICs) are the primary way in which logic gates are manufactured and used in modern electronic devices, ranging from simple calculators to sophisticated supercomputers.
