Logiikkakytkimet, or logic gates in English, are fundamental building blocks of digital circuits. They perform basic logical operations on one or more binary inputs and produce a single binary output. The output is determined by the logic function implemented by the gate. Common logic gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR. Each gate has a truth table that defines its output for all possible input combinations. For instance, an AND gate outputs 1 only if all its inputs are 1, while an OR gate outputs 1 if at least one of its inputs is 1. The NOT gate, also known as an inverter, simply flips the input, so a 0 input becomes a 1 output and vice-versa.

These gates are typically implemented using semiconductor devices like transistors. By combining different logic gates in various configurations, complex digital circuits can be created. These circuits form the basis of everything from simple calculators to sophisticated microprocessors found in computers and smartphones. Understanding the behavior and properties of logic gates is crucial for digital electronics design and the study of computer architecture. They are essential for processing information and making decisions within digital systems.
