analog systems

Analog systems process information using continuous signals that vary smoothly over time, representing data through physical quantities like voltage or frequency. Unlike digital systems that use discrete steps (bits), analog systems capture real-world phenomena—such as sound, light, or temperature—in their natural, continuous form. This allows for a more direct and often more nuanced representation of information. Examples include traditional microphones, analog watches, and radio receivers. While they can offer high fidelity for certain applications, analog systems are more susceptible to noise and degradation over distance compared to digital systems.
