Signal (electrical engineering)

A signal as referred to in communication systems, signal processing, and electrical engineering is a function that "conveys information about the behavior or attributes of some phenomenon". In the physical world, any quantity exhibiting variation in time or variation in space (such as an image) is potentially a signal that might provide information on the status of a physical system, or convey a message between observers, among other possibilities. The IEEE Transactions on Signal Processing states that the term "signal" includes audio, video, speech, image, communication, geophysical, sonar, radar, medical and musical signals.

Typically, signals are provided by a sensor, and often the original form of a signal is converted to another form of energy using a transducer. For example, a microphone converts an acoustic signal to a voltage waveform, and a speaker does the reverse.

The formal study of the information content of signals is the field of information theory. The information in a signal is usually accompanied by noise. The term noise usually means an undesirable random disturbance, but is often extended to include unwanted signals conflicting with the desired signal (such as crosstalk). The prevention of noise is covered in part under the heading of signal integrity. The separation of desired signals from a background is the field of signal recovery, one branch of which is estimation theory, a probabilistic approach to suppressing random disturbances.

Engineering disciplines such as electrical engineering have led the way in the design, study, and implementation of systems involving transmission, storage, and manipulation of information. In the latter half of the 20th century, electrical engineering itself separated into several disciplines, specialising in the design and analysis of systems that manipulate physical signals; electronic engineering and computer engineering as examples; while design engineering developed to deal with functional design of man–machine interfaces.

Signal (bridge)

In the card game of contract bridge, partners defending against a contract may play particular cards in a manner which gives a coded meaning or signal to guide their subsequent card play; also referred to as carding. Signals are usually given with the cards from the two-spot to the nine-spot. There are three types of signals:

  • attitude signals, the most frequently used, to encourage or discourage continuation of the suit lead by partner
  • count signals, showing either an even or odd number of cards held in the suit lead and
  • suit preference signals, the least frequently used, indicating partiality for a specific side suit.

The methods used for each type of signal have evolved over time and fall into two broad categories:

  • standard signals where a high card or one followed by a lower card is encouraging when an attitude signal and showing an even number of cards when a count signal; and
  • reverse or upside down signals where the meanings are reversed, i.e. a low card or one followed by a higher card is encouraging when an attitude signal and showing an even number of cards when a count signal.
Precedence of signal types

Lead is by

Following suit

Discarding |- valign=top

Partner

1. attitude
2. count

1. attitude |- valign=top

Declarer

1. count
2. suit preference

1. attitude
2. suit preference

Partnerships decide on which methods to adopt and must disclose them to their opponents. Use and interpretation is dependent upon their context, i.e. the contract, the auction, the opening lead or prior play, the cards visible in dummy, the cards visible in one's hand, who has led to the current trick and whether following suit or discarding.

Accordingly, partnerships generally have an order of precedence for the interpretation of signals such as that indicated in the adjacent table. In the vast majority of cases, the third-hand follow-suit signal is an attitude signal, but when the attitude signal does not apply, it is a count signal. Usually, it is relatively easy to recognize a signal correctly when the declarer leads – either a count signal when following suit, or an attitude signal when discarding, and when they do not apply, it is a suit-preference signal.

While signals are a means of permissible communication between defenders, they are considered as providing guiding information to partner and are not absolutely binding on him; partner may proceed otherwise as he deems rationally appropriate. Because declarer is entitled to know the meaning of all partnership agreements, including defenders' signals, he also is privy to the information being exchanged; this may give way to falsecarding tactics by the defenders.

Signal (typeface)

Signal is a script typeface, designed in 1931 by Walter Wege for H. Berthold AG in Berlin.

Designed for headlines and slogans, it was one of several typefaces inspired by brush script created in the late 1920s and early 1930s as hand-lettering went back in style. The standard version was followed up in 1932 by the bolder Block-Signal and the lighter Script-Signal. The latter was suitable for slightly longer pieces of copy. 1934 saw the release of Deutsch-Signal, based on German handwriting.

Signal (Kanon Wakeshima song)

"Signal" is the fourth single released by Japanese singer and cellist Kanon Wakeshima, and second single from her album, Tsukinami. The song "Signal" was used as the ending of the anime TV series Strike the Blood. The song reached #54 on the Oricon Singles Chart and stayed on the chart for two weeks.

Signal is a 2016 South Korean television series starring Lee Je-hoon, Kim Hye-soo and Cho Jin-woong. It aired on tvN on Fridays and Saturdays at 08:30 KST for 16 episodes between January 22 and March 12, 2016.

The series was inspired by the Hwaseong serial murders.

Signal (magazine)

Signal was a magazine published by the German Wehrmacht from 1940 through 1945.

Signal was a modern, glossy, illustrated photo journal and army propaganda tool, meant specifically for audiences in neutral, allied, and occupied countries. A German edition was distributed in Switzerland and to various other countries with a strong German military presence, but Signal was never distributed in Germany proper. The promoter of the magazine was the chief of the Wehrmacht propaganda office, Colonel Hasso von Wedel. Signal was published fortnightly (plus some special issues) in as many as 25 editions and 30 languages, and at its height had a circulation of 2,500,000 copies. It was available in the United States in English until December 1941. The last number was 6/45, only known in one sample from the Swedish edition.

Signal described the combat conditions of the German troops and their allies in all fronts, together with high quality photos, including a central double page full color one. Many of the most famous photos of World War II to be seen today are taken from Signal. The magazine also included articles about economics, science, arts, and advertising for the most well-known German companies (e.g., BMW, Agfa, Audi, Siemens, etc.). The contents of the different editions could vary, sometimes avoiding subjects that could upset or worry the population of that country (for example, the discovery of the Katyn massacre of Polish officers taken prisoners by the Soviets in 1940 was not covered by all editions). The magazine kept its independence from the Propaganda Ministry, remaining under control of the army. Still, there is a political message, one of a unified Europe (under the so-called ' New Order') fighting together against Bolshevism, this idea was symbolized by the different foreign units and volunteers fighting on the German side.

SIGNAL (programming language)

SIGNAL is a programming language based on synchronized data-flow (flows + synchronization): a process is a set of equations on elementary flows describing both data and control.

The SIGNAL formal model provides the capability to describe systems with several clocks (polychronous systems) as relational specifications. Relations are useful as partial specifications and as specifications of non-deterministic devices (for instance a non-deterministic bus) or external processes (for instance an unsafe car driver).

Using SIGNAL allows to specify an application, to design an architecture, to refine detailed components down to RTOS or hardware description. The SIGNAL model supports a design methodology which goes from specification to implementation, from abstraction to concretization, from synchrony to asynchrony.

SIGNAL has been mainly developed in INRIAEspresso team since the 1980s, at the same time as similar programming languages, Esterel and Lustre.

Signal (software)

Signal is an encrypted instant messaging and voice calling application for Android and iOS. It uses end-to-end encryption to secure all communications to other Signal users. Signal can be used to send and receive encrypted instant messages, group messages, attachments and media messages. Users can independently verify the identity of their messaging correspondents by comparing key fingerprints out-of-band. During calls, users can check the integrity of the data channel by checking if two words match on both ends of the call. A Chrome app that can link with a Signal client is also in development.

Signal is developed by Open Whisper Systems. The clients are published as free and open-source software under the GPLv3 license.
