function signal
1Signal.h — is a header file defined in the C Standard Library to specify how a program handles signals while it executes. A signal can report some exceptional behavior within the program ( such as division by zero ), or a signal can report some asynchronous …
2Signal transfer function — The signal transfer function (SiTF) is a measure of the signal output versus the signal input of a system such as an infrared system or sensor. [cite book | title = The Optical Transfer Function of Imaging Systems | author = Tom L. Williams |… …
3Signal (electrical engineering) — In the fields of communications, signal processing, and in electrical engineering more generally, a signal is any time varying or spatial varying quantity. In the physical world, any quantity measurable through time or over space can be taken as… …
4Signal to noise ratio (image processing) — The Signal to Noise Ratio (SNR) is used in image processing as a physical measure of the sensitivity of an imaging system. Industry standards measure SNR in decibels (dB) and therefore apply the 20 log rule to the pure SNR ratio. In turn,… …

6Signal Flare — is the name of several fictional characters in the various Transformers universes.Transformers: EnergonTransformers character name =Signal Flare caption =Signal Flare in Dreadwave Productions comics. affiliation =Autobot subgroup =Omnicon rank =… …
7Signal enhancement by extravascular water protons — Signal Enhancement by Extravascular water Protons, or SEEP, is a contrast mechanism for functional magnetic resonance imaging (fMRI), which is an alternative to the more commonly employed BOLD (blood oxygen level dependent) contrast. This… …
8Signal reflection — occurs when a signal is transmitted along a transmission medium, such as a copper cable or an optical fiber, some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end. This… …
9Signal lamp — training during World War II. A signal lamp (sometimes called an Aldis lamp, named after Arthur C. W. Aldis who invented a widely used design) is a visual signaling device for optical communication (typically using Morse code). Modern signal… …
10Signal transduction — In biology, signal transduction refers to any process by which a cell converts one kind of signal or stimulus into another. Most processes of signal transduction involve ordered sequences of biochemical reactions inside the cell, which are… …
