Stimulus

Theoretically, analog systems are superior to digital systems. A signal in a pure analog system can be infinitely detailed, while digital systems cannot produce signals that are more precise than their digital units. With this theoretical advantage there is a practical disadvantage, however. Since there is no limit on the potential detail signals are duplicated, until this “noise” obliterates the information embodied in the original signal.
