What is analog definition?

Analog definition refers to any device or system that uses continuous physical quantities, such as voltage, frequency, or amplitude, to represent data. Analog devices include analog clocks, analog cameras, analog tape recorders, and analog computers. Analog devices and systems are contrasted with digital devices and systems, which use discrete values, such as binary digits or digits symbolizing measurements. Analog signals are susceptible to noise and signal degradation, but they have the advantage of being able to represent a continuous range of values, making them suitable for certain types of applications, such as audio and video processing.
