21Signal Corps — The Signal Corps is a military branch, usually subordinate to a country s army, responsible for the military communications ( signals ).Many countries have a Signal Corps, whose main function is usually communication (in modern times, usually… …
22Signal instrument — A signal instrument is a musical instrument which is not (only) used for music as such, but also fit to give sound signals as a form of auditive communication, usually in open air.To make the message audible at a distance, percussion and brass… …
23Signal transduction — A basic process in molecular cell biology involving the conversion of a signal from outside the cell to a functional change within the cell. A signal (such as a hormone or neurotransmitter) interacts with a receptor on the cell surface; this… …
24function — 1. The special action or physiologic property of an organ or other part of the body. 2. To perform its special work or office, said of an organ or other part of the body. 3. The general properties of any substance, depending on its chemical …
25Signal Transfer Point — A Signal Transfer Point (STP) is a router that relays SS7 messages between signaling end points (SEPs) and other signaling transfer points (STPs). Typical SEPs include SSPs and SCPs. The STP is connected to adjacent SEPs and STPs via signaling… …
26function generator — noun An electronic device used to generate a signal representing the periodic value of a given mathematical function, especially sine, square, triangle and sawtooth waveforms …
27Sampling (signal processing) — Signal sampling representation. The continuous signal is represented with a green color whereas the discrete samples are in blue. In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the …
28Window function — For the term used in SQL statements, see Window function (SQL) In signal processing, a window function (also known as an apodization function or tapering function[1]) is a mathematical function that is zero valued outside of some chosen interval …
29Analytic signal — Not to be confused with Analytic function. In mathematics and signal processing, the analytic representation of a real valued function or signal facilitates many mathematical manipulations of the signal. The basic idea is that the negative… …
30Wigner distribution function — The Wigner distribution function (WDF), named after Eugene Wigner, was first proposed for corrections to classical statistical mechanics in 1932 by Eugene Wigner. But the Wigner distribution function is also a good transform for time frequency… …
