"Bessel" typically refers to the German mathematician and astronomer Friedrich Bessel, known for his work in astronomy and the development of Bessel functions, which are solutions to Bessel's differential equation. These functions have applications in various fields, including physics, engineering, and signal processing. Additionally, "Bessel" may also refer to Bessel filters, a type of electronic filter that maintains a maximally flat group delay.
