Analog electronics deal with systems that process , where voltages and currents vary smoothly to represent real-world information like sound, light, or temperature . Unlike digital circuits that use binary "on/off" states, analog circuits work with a proportional relationship between the physical quantity and the electrical signal. Core Components
Analog circuits are built using a combination of passive and active components: Analog vs. Digital - SparkFun Learn Analog Electronics. Analog Circuitry Explained
