lülitusfunktsioonid

Lülitusfunktsioonid, also known as switching functions or Boolean functions, are mathematical functions used in digital logic and computer science. They operate on binary inputs, meaning they accept only values of 0 or 1 (often representing false or true, or off or on). The output of a switching function is also a binary value. These functions form the fundamental building blocks of all digital circuits and computational processes.

The operations performed by switching functions are typically logical operations such as AND, OR, and NOT. The AND function outputs 1 only if all its inputs are 1. The OR function outputs 1 if at least one of its inputs is 1. The NOT function, a unary operator, inverts its input, so 0 becomes 1 and 1 becomes 0. More complex functions can be constructed by combining these basic operations.

Switching functions are often represented using truth tables, which list all possible combinations of input values and the corresponding output for each combination. They can also be expressed algebraically using Boolean algebra, or graphically using logic gates. Understanding and manipulating switching functions is crucial for designing digital systems, from simple logic circuits to complex microprocessors. They are the basis for decision-making and information processing in digital electronics.
