Frequency Response

The frequency response of a system is a measurement that indicates how a system responds to different input frequencies; it is commonly used to characterize physical systems during their design, testing, and use. This entry first describes how the frequency response of a system is measured in practice. It then focuses on voice production, specifically the frequency response of the vocal tract and the physiology of how the ear analyzes the frequency content of incoming sounds.

In engineering and physics, the measurement of and reference to the frequency response of systems are commonplace since frequency response provides a way not only to specify how a given physical system will respond to various inputs during the design phase, it also provides a practical means of testing to ...
