What is Analog Information ?
Definition: What Does the Term Acceleration Mean?
Analog and digital signals are often confused.
Analog information is an older, more dated type of means of visually showing a measurement. Analog is from the term analogy, which is the method of showing a reading such as temperature, pressure, etc. by the use of another medium. Any dial that shows a temperature based upon a physical method of identification, such as mercury rising in a thermometer is an analog signal. Analog is a representation of the item being measured.
