Loogikakomponenten

Loogikakomponenten, also known as logic gates, are fundamental building blocks of digital circuits. They are electronic circuits that perform a basic logical operation on one or more binary inputs and produce a single binary output. The output is determined by the input values and the specific logic function the gate implements. The most common logic gates are AND, OR, NOT, NAND, NOR, XOR, and XNOR.

An AND gate outputs a 1 only if all its inputs are 1. An OR gate outputs a 1 if at least one of its inputs is 1. A NOT gate, also called an inverter, has a single input and outputs the opposite of that input; if the input is 1, the output is 0, and vice versa. NAND gates (NOT-AND) and NOR gates (NOT-OR) are the complements of AND and OR gates, respectively. XOR (exclusive OR) gates output 1 if an odd number of inputs are 1, meaning the inputs are different. XNOR gates (exclusive NOR) output 1 if the inputs are the same.

These simple components are combined in various configurations to create more complex digital circuits, such as adders, multiplexers, flip-flops, and ultimately, microprocessors. The design and analysis of digital systems rely heavily on understanding the behavior and interconnection of logic gates. They are the basis for all modern digital computation and electronics.
