For analog signals, signal processing may involve the amplification and filtering of audio signals for audio equipment or the modulation and demodulation of signals for telecommunications.

In telecommunications, modulation is the process of conveying a message signal, for example a digital bit stream or an analog audio signal, inside another signal that can be physically transmitted.

Distinguishing delivery method from the media distributed applies specifically to telecommunications networks, as most other delivery systems are either inherently streaming ( e. g., radio, television ) or inherently nonstreaming ( e. g., books, video cassettes, audio CDs ).

In audio system measurements, telecommunications and other areas where the measurand is a signal that swings above and below a zero value but is not sinusoidal, peak amplitude is often used.

In telecommunications and professional audio, a balanced line or balanced signal pair is a transmission line consisting of two conductors of the same type, each of which have equal impedances along their lengths and equal impedances to ground and to other circuits.

In telecommunication, a carrier system ( loosely, a synonym with carrier ) is a multichannel telecommunications system in which a number of individual channels ( e. g. data, audio, video or combination thereof ) are multiplexed for transmission.

Pre-emphasis is commonly used in telecommunications, digital audio recording, record cutting, in FM broadcasting transmissions, and in displaying the spectrograms of speech signals.

In telecommunications, squelch is a circuit function that acts to suppress the audio ( or video ) output of a receiver in the absence of a sufficiently strong desired input signal.

Simply due to costs, teleconferences are frequently limited to audio links ( telephone or computer-based ). A teleconference or teleseminar is the live exchange and mass articulation of information among several persons and machines remote from one another but linked by a telecommunications system.

The telecommunications system may support the teleconference by providing one or more of the following: audio, video, and / or data services by one or more means, such as telephone, computer, telegraph, teletypewriter, radio, and television.

Although those " hybrid " techniques are usually more common in telecommunications systems than in consumer audio, their existence alone blurs the distinctive line between certain digital and analog systems, at least for what regards some of their alleged advantages or disadvantages.

Videoconferencing uses audio and video telecommunications to bring people at different sites together.

Nonlinear distortion is a term used ( in fields such as electronics, audio and telecommunications ) to describe the phenomenon of a non-linear relationship between the " input " and " output " signals of-for example-an electronic device.

Typically, a television network, TV station, or other originator of video programming transmits SMPTE color bars together with a continuous 1000 Hz audio tone before sending program material, in order to assert ownership of the transmission line or medium, and so that receiving stations and intermediary telecommunications providers may adjust their equipment.

It has been claimed that Stubblefield invented the radio before either Nikola Tesla or Guglielmo Marconi, but his devices seem to have worked by audio frequency induction or, later, audio frequency earth conduction ( creating disturbances in the near-field region ) rather than by radio frequency radiation for radio transmission telecommunications.

* Bantam Jack, 4. 4 mm ( 0. 173-inch ) diameter connector used in professional audio or telecommunications.

This category, personal computers, contains articles related to those microcomputers ( intended for ) being used by individual people primarily for ( home ) office / productivity applications and telecommunications ( even though uses such as computer gaming, music audio processing / playback, and photo / video editing are also a significant, and growing, part of personal computer user activities ).

By 1942, the company had designed a sophisticated audio system for the University of Minnesota, and the resulting jacks, plugs, patch cords and jackfields became the cornerstones for ADC's later entry into telecommunications.

Upgraded stereo systems use a JBL audio system, and certain navigation packages come with a telecommunications system with Hyundai's Mozen system.

LEMO is both the name of an electronic and fibre optic connector manufacturer, based in Switzerland, and the name commonly used to refer to push-pull connectors made by that company, which are used in medical, industrial, audio / visual, telecommunications, military, scientific research and measurement applications.

In applications where response time is critical, such as telecommunications network equipment, main memory databases are often used.

In the field of telecommunications, weighting filters are widely used in the measurement of electrical noise on telephone circuits, and in the assessment of noise as perceived through the acoustic response of different types of instrument ( handset ).

** Planning, Training, and Exercise Support ( PTE )-Our mission is to ensure NCS readiness, enhance partnerships within government and industry, coordinate telecommunications operational planning among NCS elements, develop emergency response requirements, and to provide skilled civilians and reservists during crises and emergencies.

* In telecommunications, a negative-acknowledge character ( NAK or NACK ) is a transmission control character sent by a station as a negative response to the station with which the connection has been set up.

* Output or response, the result of telecommunications input

One response is that some countries have a Universal Service Fund and have all their telecommunications industries pay a part of their net earnings into it.

It was specified by Nordic telecommunications administrations ( PTTs ) and opened for service in 1 October 1981 as a response to the increasing congestion and heavy requirements of the manual mobile phone networks: ARP ( 150 MHz ) in Finland and MTD ( 450 MHz ) in Sweden and Denmark and OLT in Norway.

In telecommunications, equalizers are used to render the frequency response — for instance of a telephone line — flat from end-to-end.

* Interactive voice response ( also Audio or Automated response unit ), a telecommunications device

The product became popular for telecommunications equipment, as response times in the milliseconds or even microseconds were required for applications like packet switching.

* Callback ( telecommunications ), the telecommunications event that occurs when the originator of a call is immediately called back in a second call as a response

In telecommunications, a callback ( also written as call-back ) occurs when the originator of a call is immediately called back in a second call as a response.

Moran has represented the $ 200 million salmon farming industry in Atlantic Canada ; was a strategist behind a lobbying campaign in response to the closure of a Canadian Forces Base that enabled the community obtain operating control of a valuable economic asset ; led a Federal / Provincial Government Industrial Adjustment Committee to deal with the closure of the Campbell Soup plant ; managed a hospital restructuring study for the Ontario Ministry of Health ; developed a strategic plan to position the telecommunications industry as an important voice in the lobby for competition in long distance telephone services ; managed a Feasibility Study – Business Plan Report prepared to preserve a historic Canadian Pacific Railway Station ; and developed a strategic plan to position a not-for-profit recycling business as a leading edge environmental and sustainable development company.

( 3 ) Nothing in this section shall require that the design of, or design and selection of parts and components for, a consumer electronics, telecommunications, or computing product provide for a response to any particular technological measure, so long as such part or component, or the product in which such part or component is integrated, does not otherwise fall within the prohibitions of subsection ( a )( 2 ) or ( b )( 1 ).
