Digital logic circuits are the building blocks of modern electronic devices. They use binary signals, represented as 0s and 1s, to perform various operations. These circuits can be simple, like AND and OR gates, or complex, like flip-flops and multiplexers. They process information by combining these basic gates to create more intricate functions. These circuits are essential in devices such as computers, smartphones, and digital watches. They enable tasks like data storage, processing, and communication. By manipulating binary data, digital logic circuits help execute instructions and manage the flow of information in electronic systems.
