Adjacent-channel interference

Adjacent-channel interference (ACI) is interference caused by extraneous power from a signal in an adjacent channel.

See Pilot signal and Adjacent-channel interference

AM stereo

AM stereo is a term given to a series of mutually incompatible techniques for radio broadcasting stereo audio in the AM band in a manner that is compatible with standard AM receivers.

See Pilot signal and AM stereo

Audio frequency

An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human.

See Pilot signal and Audio frequency

Bandwidth (signal processing)

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies.

See Pilot signal and Bandwidth (signal processing)

Baseband

In telecommunications and signal processing, baseband is the range of frequencies occupied by a signal that has not been modulated to higher frequencies.

See Pilot signal and Baseband

C0 and C1 control codes

The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII.

See Pilot signal and C0 and C1 control codes

Carrier wave

In telecommunications, a carrier wave, carrier signal, or just carrier, is a periodic waveform (usually sinusoidal) that carries no information that has one or more of its properties modified (the called modulation) by an information-bearing signal (called the message signal or modulation signal) for the purpose of conveying information.

See Pilot signal and Carrier wave

Color television

Color television (American English) or colour television (Commonwealth English) is a television transmission technology that includes color information for the picture, so the video image can be displayed in color on the television set.

See Pilot signal and Color television

Colorburst

Colorburst is an analog and composite video signal generated by a video-signal generator used to keep the chrominance subcarrier synchronized in a color television signal.

See Pilot signal and Colorburst

Communications system

A communications system or communication system is a collection of individual telecommunications networks systems, relay stations, tributary stations, and terminal equipment usually capable of interconnection and interoperation to form an integrated whole.

See Pilot signal and Communications system

Data Radio Channel

Data Radio Channel (DARC) is a high-rate (16 kbit/s) standard for encoding data in a subcarrier over FM radio broadcasts.

See Pilot signal and Data Radio Channel

Equalization (communications)

In telecommunication, equalization is the reversal of distortion incurred by a signal transmitted through a channel.

See Pilot signal and Equalization (communications)

FM broadcasting

FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave.

See Pilot signal and FM broadcasting

Frequency

Frequency (symbol f), most often measured in hertz (symbol: Hz), is the number of occurrences of a repeating event per unit of time.

See Pilot signal and Frequency

Frequency modulation

Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave.

See Pilot signal and Frequency modulation

Guard band

In telecommunications, a guard band is a narrow, intentionally unused frequency band that is placed between adjacent frequency bands to minimize interference between them.

See Pilot signal and Guard band

Harmonic

In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal.

See Pilot signal and Harmonic

Hearing

Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium.

See Pilot signal and Hearing

Hertz

The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second.

See Pilot signal and Hertz

Infrasound

Infrasound, sometimes referred to as low frequency sound, describes sound waves with a frequency below the lower limit of human audibility (generally 20 Hz, as defined by the ANSI/ASA S1.1-2013 standard).

See Pilot signal and Infrasound

Modulation

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted.

See Pilot signal and Modulation

Multichannel Television Sound

Multichannel Television Sound (MTS) is the method of encoding three additional audio channels into analog 4.5 MHz audio carriers on System M and System N. It was developed by the Broadcast Television Systems Committee, an industry group, and sometimes known as BTSC as a result.

See Pilot signal and Multichannel Television Sound

Narrowband

Narrowband signals are signals that occupy a narrow range of frequencies or that have a small fractional bandwidth.

See Pilot signal and Narrowband

NTSC

NTSC (from National Television Standards Committee) is the first American standard for analog television, published in 1941.

See Pilot signal and NTSC

PAL

Phase Alternating Line (PAL) is a colour encoding system for analog television.

See Pilot signal and PAL

Pilottone

Pilottone (or Pilotone) and the related neo-pilotone are special synchronization signals recorded by analog audio recorders designed for use in motion picture production, to keep sound and film recorded on separate media (otherwise known as double system recording) synchronised. Pilot signal and Pilottone are synchronization.

Quadrature amplitude modulation

Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information.

Radio Data System

Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts.

See Pilot signal and Radio Data System

Radio relay

Radio stations that cannot communicate directly due to distance, terrain or other difficulties sometimes use an intermediate radio relay station to relay the signals.

See Pilot signal and Radio relay

Reference

A reference is a relationship between objects in which one object designates, or acts as a means by which to connect to or link to, another object.

See Pilot signal and Reference

SECAM

SECAM, also written SÉCAM (Séquentiel de couleur à mémoire, French for color sequential with memory), is an analog color television system that was used in France, Russia and some other countries or territories of Europe and Africa.

See Pilot signal and SECAM

Sideband

In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, that are the result of the modulation process.

See Pilot signal and Sideband

Signaling (telecommunications)

In telecommunication, signaling is the use of signals for controlling communications.

Stereophonic sound

Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective.

See Pilot signal and Stereophonic sound

Synchronization

Synchronization is the coordination of events to operate a system in unison.

See Pilot signal and Synchronization

Syncword

In computer networks, a syncword, sync character, sync sequence or preamble is used to synchronize a data transmission by indicating the end of header information and the start of data. Pilot signal and syncword are synchronization.

See Pilot signal and Syncword

Telecommunications

Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information with an immediacy comparable to face-to-face communication.

See Pilot signal and Telecommunications

Time base correction

Time base correction (TBC) is a technique to reduce or eliminate errors caused by mechanical instability present in analog recordings on mechanical media.

See Pilot signal and Time base correction

Video 2000

Video 2000 (also known as V2000, with the tape standard Video Compact Cassette, or VCC) is a consumer videocassette system and analogue recording standard developed by Philips and Grundig to compete with JVC's VHS and Sony's Betamax video technologies.
