Analog systems are types of systems that process information in a continuous manner. Unlike digital systems, which use discrete values (like 0s and 1s), analog systems represent data through 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 analog clocks, thermometers, and vinyl record players. These systems can provide a more natural representation of real-world phenomena, but they are often more susceptible to noise and distortion compared to their digital counterparts.
