Analog electronics refers to the branch of electronics that deals with continuously variable signals. Unlike digital electronics, which use discrete values (0s and 1s), analog systems process signals that can represent a range of values. Common components in analog electronics include resistors, capacitors, and transistors, which work together to amplify, filter, and modulate signals. In everyday applications, analog electronics are found in devices like radios, televisions, and audio equipment. These devices rely on analog signals to transmit sound and images. Understanding analog electronics is essential for designing and troubleshooting various electronic systems, as they form the foundation for many modern technologies.
