Engineers realized that the vibration from the aircraft reduced the error from sticky moving parts. Instead of moving in short jerks, they moved more continuously. Small vibrating motors were built into the computers, and their vibration was called dither from the Middle English verb “didderen,” meaning “to tremble. Today, when you tap a mechanical meter to increase its accuracy, you are applying dither, and modern dictionaries define dither as a highly nervous, confused, or agitated state.
In minute quantities, dither successfully makes a digitization system a little more analog in the good sense of the word. By 1964 dither was being used in the modern sense described in this article. Dither is often used in digital audio and video processing. It is utilized in many different fields where digital processing and analysis are used. In some fields, especially where the receptor is sensitive to such artifacts, cyclical errors yield undesirable artifacts.
