Analog devices are a combination of analog machines and analog media that have the ability to record, measure, broadcast, and reproduce continuous data.
An analog or continuous signal can have an infinite number of values (that it can assume). As a result, the only limitation on the resolution is the analog device's accuracy.
Non-electrical analog devices and electrical analog devices are the two categories of analog devices.
Non-electrical analog devices include pendulums, analog watches, clocks, steam engine governors, and acoustic rangefinders.
Analog televisions and computers are two examples of electrical analog devices.
A digital to analog converter is a circuit that can convert a digital signal to an analog signal.
