logiikkatoiminnot

Logiikkatoiminnot, known in English as logic gates, are fundamental building blocks of digital circuits. They perform basic logical operations on one or more binary inputs to produce a single binary output. The most common logic functions include AND, OR, NOT, NAND, NOR, XOR, and XNOR.

The AND gate outputs a 1 only if all of its inputs are 1. The OR gate outputs a 1 if at least one of its inputs is 1. The NOT gate, also known as an inverter, has a single input and outputs the opposite of that input; if the input is 0, the output is 1, and vice versa.

NAND (Not AND) and NOR (Not OR) gates are the complements of AND and OR gates, respectively. A NAND gate outputs 0 only if all its inputs are 1, otherwise it outputs 1. A NOR gate outputs 1 only if all its inputs are 0, otherwise it outputs 0. XOR (Exclusive OR) gates output 1 if an odd number of inputs are 1. XNOR (Exclusive NOR) gates output 1 if an even number of inputs are 1.

These logic gates are implemented using electronic components like transistors. By combining different logic gates in complex arrangements, engineers can create sophisticated digital systems such as microprocessors, memory units, and control circuits that power all modern electronic devices. Understanding logiikkatoiminnot is crucial for anyone studying digital electronics or computer engineering.
