Analog Signal
An analog signal is a type of signal that represents information through continuous variations. Unlike digital signals, which use discrete values (like 0s and 1s), analog signals can take on an infinite range of values within a given range. A common example is a vinyl record, where the grooves correspond to sound waves, capturing the nuances of the audio. Analog signals are used in many areas, including music, radio, and television, reflecting the smooth and continuous nature of the information they carry, making them a fundamental part of various communication technologies.

An analog signal is a continuous signal that represents information in a varying form, such as electrical voltage or sound waves. Unlike digital signals, which only use discrete values (like 0s and 1s), analog signals can take on a wide range of values. This means they can smoothly transition between states, capturing nuances in sound, light, or temperature. Common examples include the sound from a vinyl record or radio waves. Analog technology is often praised for its richness and warmth, though it can be more susceptible to interference and noise compared to digital systems.
