Logiikkagateilla

Logiikkagateilla, also known as logic gates, are fundamental building blocks in digital electronics and computer science. They are simple electronic circuits that perform basic logical operations on one or more binary inputs to produce a single binary output. The two primary states of a binary input or output are typically represented by the symbols 0 and 1, which correspond to the voltages or currents in the circuit.

The most common types of logic gates include:

AND gate: Produces an output of 1 only if all inputs are 1.

OR gate: Produces an output of 1 if at least one input is 1.

NOT gate: Produces an output that is the complement of the input (i.e., 1 if the input is 0, and 0 if the input is 1).

NAND gate: The complement of the AND gate, producing an output of 0 only if all inputs are 1.

NOR gate: The complement of the OR gate, producing an output of 0 if at least one input is 1.

XOR gate: Produces an output of 1 if the number of 1 inputs is odd.

XNOR gate: The complement of the XOR gate, producing an output of 1 if the number of 1 inputs is even.

Logic gates are used to build more complex digital circuits, such as arithmetic logic units (ALUs), flip-flops, and memory cells. They are essential in the design and implementation of digital systems, including computers, smartphones, and other electronic devices. The behavior of logic gates is typically described using truth tables, which list all possible combinations of inputs and the corresponding outputs.
