combinational circuits

Combinational circuits are electronic systems that process input signals to produce output signals based solely on the current inputs. They do not have memory or feedback, meaning the output is determined only by the current inputs at any given time. Common examples include adders, which perform arithmetic operations, and multiplexers, which select data from multiple sources. These circuits are foundational in digital electronics, enabling devices such as computers and calculators to perform complex functions by combining basic logical operations (like AND, OR, and NOT). Their simplicity and speed make them essential in many technological applications.
