Analog electronics is a branch of electronics that deals with continuously variable signals. Unlike digital electronics, which uses 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. These systems are widely used in various applications, such as audio equipment, radio communications, and television broadcasting. Analog electronics plays a crucial role in converting real-world phenomena, like sound and light, into electrical signals that can be manipulated and transmitted.
