Industry:Telecommunications
A track with a spiral shape written on a diskette, as part of a method of copy protection.
Industry:Telecommunications
A transcoding of the form ADPCM-PCM-ADPCM (adaptive differential pulse code modulation-pulse code modulation-adaptive differential pulse code modulation) when there are no transmission errors and the integrity of the bit stream is preserved.
Industry:Telecommunications
A transducer capable of accepting an optical signal and producing an electrical signal containing the same information as in the optical signal. Note: The two main types of semiconductor photodetectors are the photodiode (PD) and the avalanche photodiode (APD. )
Industry:Telecommunications
A transducer that generates an output signal when irradiated with optical energy.
Industry:Telecommunications
A transient disturbance to, or momentary interruption of, a communication channel, power supply (especially that provided via a commercial electric power distribution network or grid, but not limited to same,) etc. 2. A match of a data item to a prescribed criterion or criteria. Note: For example, each of the matches from a search engine is called a "hit. " 3. The access of any item, such as a page or a graphic image, from a Web server. Note 1: Hits are recorded for the purpose of assessing traffic/interest in a web site; many web sites have a commercial sponsor who pays a small amount per hit for displaying the commercial advertisement on that site.
