CX is a noise reduction system for recorded analog signal, analog audio. It was developed by CBS Laboratories (a division of CBS) in the late 1970s as a low-cost competitor to other noise reduction (NR) systems such as dbx disc and High-Com II, and was officially introduced in 1981. The name ''CX'' was derived from "Compatible eXpansion", a feature of the technique. __TOC__ Use on vinyl LP records CX was originally designed by CBS as a noise-reduction technology for vinyl LP records, similar to the earlier dbx disc (based on dbx II) and High-Com II systems, but, like the later UC (noise reduction), UC system, it aimed at the lower-cost consumer mass market rather than high-end audiophile niche markets only. CX-encoded records required a special CX expander connected to a stereo system, in order to fully reproduce the CX encoded sound on the LP. However, in contrast to dbx disc and High-Com II, CX-encoded records, like UC-encoded records, could also b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-Com II
The High Com (also as HIGH COM, both written with a thin space) noise reduction system was developed by Telefunken, Germany, in the 1970s as a high quality high compression analogue compander for audio recordings. High Com The idea of a compander for consumer devices was based on studies of a fixed two-frequency band, band compander by Jürgen Wermuth of AEG-Telefunken ELA, Wolfenbüttel, developer of the Telefunken (formally abbreviated as "TEL" in professional broadcasting) four-band audio compander for professional use. In April 1974, the resulting "RUSW-200" prototype first led to the development of a sliding two-band compander by Ernst F. Schröder of Telefunken Grundlagenlaboratorium, Hannover since July 1974. However, the finally released High Com system, which was marketed by Telefunken since 1978, worked as a broadband 2:1:2 compander, achieving almost 15 Decibel, dB of noise reduction for low and up to 20 dB Root ...

Operational Amplifier
An operational amplifier (often op amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. In this configuration, an op amp produces an output potential (relative to circuit ground) that is typically 100,000 times larger than the potential difference between its input terminals. The operational amplifier traces its origin and name to analog computers, where they were used to perform mathematical operations in linear, non-linear, and frequency-dependent circuits. The popularity of the op amp as a building block in analog circuits is due to its versatility. By using negative feedback, the characteristics of an op-amp circuit, its gain, input and output impedance, bandwidth etc. are determined by external components and have little dependence on temperature coefficients or engineering tolerance in the op amp itself. Op amps are used widely in electronic devices today, including a vast array of consumer, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breathing (noise Reduction)
Breathing (or ventilation) is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen. All aerobic creatures need oxygen for cellular respiration, which extracts energy from the reaction of oxygen with molecules derived from food and produces carbon dioxide as a waste product. Breathing, or "external respiration", brings air into the lungs where gas exchange takes place in the alveoli through diffusion. The body's circulatory system transports these gases to and from the cells, where "cellular respiration" takes place. The breathing of all vertebrates with lungs consists of repetitive cycles of inhalation and exhalation through a highly branched system of tubes or airways which lead from the nose to the alveoli. The number of respiratory cycles per minute is the breathing or respiratory rate, and is one of the four primary vital signs of life. Under normal conditions th ...

Pumping (noise Reduction)
Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio. All signal processing devices, both analog and digital, have traits that make them susceptible to noise. Noise can be random with an even frequency distribution (white noise), or frequency-dependent noise introduced by a device's mechanism or signal processing algorithms. In electronic systems, a major type of noise is ''hiss'' created by random electron motion due to thermal agitation. These agitated electrons rapidly add and subtract from the output signal and thus create detectable noise. In the case of photographic film and magnetic tape, noise (both visible and audible) is introduced due to the grain structure of the medium. In photograp ...

''Olivia Physical'' is a 1982 video collection featuring the singer Olivia Newton-John and various of her songs, most from the album ''Physical (Olivia Newton-John album), Physical''. A somewhat expanded version of the video was aired as an American Broadcasting Company, ABC prime-time television special, ''Let's Get Physical'', which was in the top 10 of the Nielsen ratings.

Olivia Newton-John
Dame Olivia Newton-John (26 September 1948 – 8 August 2022) was a British-Australian singer, actress and activist. She was a four-time Grammy Award winner whose music career included 15 top-ten singles, including 5 number-one singles on the ''Billboard'' Hot 100 and two number-one albums on the ''Billboard'' 200: ''If You Love Me, Let Me Know'' (1974) and ''Have You Never Been Mellow'' (1975).

In 1978, Newton-John starred in the musical film '' Grease'', which was the highest-grossing musical film at the time and whose soundtrack remains one of the world's best-selling albums. It features two major hit duets with co-star John Travolta: "You're the One That I Want"—which is one of the best-selling singles of all time—and " Summer Nights".

Capacitance Electronic Disc
The Capacitance Electronic Disc (CED) is an analog video, analog video disc playback system developed by RCA, in which video and audio could be played back on a TV set using a special stylus and high-density groove system similar to phonograph records. First conceived in 1964, the CED system was widely seen as a technological success which was able to increase the density of a long-playing record by two Order of magnitude#Uses, orders of magnitude. Despite this achievement, the CED system fell victim to poor planning, various conflicts with RCA management, and several technical difficulties that slowed development and stalled production of the system for 17 years—until 1981, by which time it had already been made obsolete by laser videodisc (DiscoVision, later called LaserVision and LaserDisc) as well as Betamax and VHS Videotape, video cassette formats. Sales for the system were nowhere near projected estimates. In the spring of 1984, RCA announced it was discontinuing player ...

SelectaVision
SelectaVision was a trademark name used on four classes of device by RCA: * The Holotape, a prototype video medium * Magnetic tape * VHS videocassette recorders, and * Capacitance Electronic Disc videodisc players and the discs themselves. Capacitance Electronic Disc's competitors, Philips/Magnavox and Pioneer, instead manufactured optical discs, read with lasers. On April 4, 1984, RCA, having sold only 550,000 players, ended sales, losing $580 million. The losses resulted in General Electric's acquisition of RCA in 1986, and the "SelectaVision" brand was abandoned.
