Analog Circuits

Analog circuits are electronic systems that process continuous signals, meaning the information they handle can vary smoothly over a range. Unlike digital circuits that work with specific, discrete values (like 0s and 1s), analog circuits manipulate real-world signals such as sound, light, or temperature. They amplify, filter, or modify these signals to capture, transmit, or improve information—for example, in audio equipment or radios. These circuits rely on components like resistors, capacitors, and transistors to perform their functions smoothly across a range of values, allowing seamless interaction with natural signals.
