• Signal integrity — or SI is a measure of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. Over short distances and at low bit rates, a simple conductor can transmit this with… …   Wikipedia

• Signal 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… …   Wikipedia

• Signal bleed — is a term used to describe filters, usually for cable television, not blocking targeted channel as designed. The term came to public awareness as more channels with adult material began to be available on cable television services and,… …   Wikipedia

• Signal 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… …   Wikipedia

• Signal (bridge) — In the card game of contract bridge, partners defending against a contract may play particular cards in a manner which gives a signal or coded meaning to guide their subsequent card play; also referred to as carding. Contents 1 Standard signals 1 …   Wikipedia

• Signal subspace — In signal processing, signal subspace methods are empirical linear methods for dimensionality reduction and noise reduction. These approaches have attracted significant interest and investigation recently in the context of speech enhancement,… …   Wikipedia

• Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… …   Wikipedia

• Signal strength — In telecommunications, particularly in radio, signal strength refers to the magnitude of the electric field at a reference point that is a significant distance from the transmitting antenna. It may also be referred to as received signal level or… …   Wikipedia

• Signal (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… …   Wikipedia

• Signal-flow graph — A signal flow graph (SFG) is a special type of block diagram[1] and directed graph consisting of nodes and branches. Its nodes are the variables of a set of linear algebraic relations. An SFG can only represent multiplications and additions.… …   Wikipedia

• Signal conditioning — In electronics, signal conditioning means manipulating an analogue signal in such a way that it meets the requirements of the next stage for further processing. For example, the output of an electronic temperature sensor, which is probably in the …   Wikipedia
