51Railway semaphore signal — One of the earliest forms of fixed railway signal is the semaphore. These signals display their different indications to train drivers by changing the angle of inclination of a pivoted arm . Semaphore signals were patented in the early 1840s by… …
52Analog signal processing — is any signal processing conducted on analog signals by analog means. Analog indicates something that is mathematically represented as a set of continuous values. This differs from digital which uses a series of discrete quantities to represent… …
53Video signal generator — A video signal generator is a type of signal generator which outputs predetermined video and/or television waveforms, and other signals used to stimulate faults in, or aid in parametric measurements of, television and video systems. There are… …
54Automatic Block Signal — Basic Automatic Block Signals = Automatic Block Signal, or ABS, systems consist of a series of signals that govern blocks of track between the signals. The signals are automatically activated by the conditions of the block beyond the signal.… …
55Digital signal processor — A Digital Signal Processor chip found in a guitar effects unit. A digital signal processor (DSP) is a specialized microprocessor with an architecture optimized for the fast operational needs of digital signal processing.[1] …
56Clock signal — In electronics and especially synchronous digital circuits, a clock signal is a particular type of signal that oscillates between a high and a low state and is utilized like a metronome to coordinate actions of circuits. Although the word signal… …
57Processeur de signal numérique — Un DSP (de l anglais « Digital Signal Processor », qu on pourrait traduire par « processeur de signal numérique ») est un microprocesseur optimisé pour les calculs. Son application principale est le traitement numérique du… …
58Digital Signal 1 — (DS1, sometimes DS 1) is a T carrier signaling scheme devised by Bell Labs.[1] DS1 is a widely used standard in telecommunications in North America and Japan to transmit voice and data between devices. E1 is used in place of T1 outside North… …
59Power Good Signal — In addition to the voltages and currents that a computer needs to operate, power supplies also provide a signal called the Power Good signal, sometimes written as Power OK or Power Good. Its purpose is to tell the computer all is well with the… …
60Disturbance voltage — In telecommunication, a disturbance voltage is an unwanted voltage induced in a system by natural or man made sources. In telecommunications systems, the disturbance voltage creates currents that limit or interfere with the interchange of… …
