loogikaväravate

Loogikaväravate, also known as logic gates, are fundamental building blocks in digital circuits and computer systems. They perform logical operations on one or more binary inputs to produce a single binary output. The basic logic gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR gates. Each gate has a specific truth table that defines the output for every possible combination of inputs.

The AND gate produces a true output only when all inputs are true. The OR gate produces a true output if at least one input is true. The NOT gate, also known as an inverter, produces the opposite of the input. The NAND gate is the inverse of the AND gate, and the NOR gate is the inverse of the OR gate. The XOR gate, or exclusive OR, produces a true output only when the inputs are different. The XNOR gate, or exclusive NOR, produces a true output only when the inputs are the same.

Logic gates can be combined to create more complex circuits, such as adders, multiplexers, and flip-flops. They are essential in the design of digital systems, including microprocessors, memory chips, and communication devices. The reliability and efficiency of these systems depend on the proper functioning of logic gates. Advances in technology have led to the development of smaller, faster, and more energy-efficient logic gates, contributing to the ongoing miniaturization and increased performance of electronic devices.
