Analog systems are types of technology that process information in a continuous manner. Unlike digital systems, which use discrete values (like 0s and 1s), analog systems represent data through varying physical quantities, such as voltage or current. This allows them to capture a wide range of values, making them suitable for applications like audio and video signals. Common examples of analog systems include vinyl records, analog clocks, and thermometers. These systems can provide a more natural representation of certain types of data, but they are often more susceptible to noise and distortion compared to their digital counterparts.
