Transmission curve
Transmission of a signal or filter as a function of frequency or wavelength From Wikipedia, the free encyclopedia

The transmission curve or transmission characteristic[1] is the mathematical function or graph that describes the transmission fraction of an optical or electronic filter as a function of frequency or wavelength.[2] It is an instance of a transfer function but, unlike the case of, for example, an amplifier, output never exceeds input (maximum transmission is 100%). The term is often used in commerce,[3] science,[4] and technology[5] to characterise filters.
The term has also long been used in fields such as geophysics and astronomy to characterise the properties of regions through which radiation passes, such as the ionosphere.[6][7]
