Definition

1. Noun:

   • Something having the property of being analogous to something else: An analogue is an object, idea, or system that is similar to another in function or form, allowing for comparison. It is often used to explain something unfamiliar by relating it to something familiar.
   • A thing which is comparable to something else in significant respects: In technology and science, it can refer to a physical representation of information, such as a watch with hands, as opposed to a digital display.

2. Adjective:

   • Of a circuit or device having an output that is proportional to the input: Describing a system where data is represented by continuously variable physical quantities, like the position of a needle or the voltage in a wire, rather than discrete numbers.
