Encyclopedia > Data signaling rate

In telecommunication, data signaling rate (DSR) is the aggregate rate at which data pass a point in the transmission path of a data transmission system. BlackBerry 7100t Telecommunication refers to communication over long distances. ... Data is the plural of datum. ... In communications, transmission is the act of transmitting electrical messages (and the associated phenonomena of radiant energy that pass through media). ... A path is a route between two points. ... In telecommunications a transmission system is a system that transmits a signal from one place to another. ...


Notes:

  1. The DSR is usually expressed in bits per second.
  2. The data signaling rate is given by where m is the number of parallel channels, ni is the number of significant conditions of the modulation in the I-th channel, and Ti is the unit interval, expressed in seconds, for the I-th channel.
  3. For serial transmission in a single channel, the DSR reduces to (1/T)log2n; with a two-condition modulation, i. e. n =2, the DSR is 1/T.
  4. For parallel transmission with equal unit intervals and equal numbers of significant conditions on each channel, the DSR is (m /T)log2 n; in the case of a two-condition modulation, this reduces to m /T.
  5. The DSR may be expressed in bauds, in which case, the factor log2ni in the above summation formula should be deleted when calculating bauds.
  6. In synchronous binary signaling, the DSR in bits per second may be numerically the same as the modulation rate expressed in bauds. Signal processors, such as four-phase modems, cannot change the DSR, but the modulation rate depends on the line modulation scheme, in accordance with Note 4. For example, in a 2400 bit/s 4-phase sending modem, the signaling rate is 2400 bit/s on the serial input side, but the modulation rate is only 1200 bauds on the 4-phase output side.

See also: bit rate, transfer rate. In telecommunications and computing, bit rate (sometimes written bitrate) is the frequency at which bits are passing a given (physical or metaphorical) point. It is quantified using the bit per second (bit/s) unit. ... In information theory, a signal is a flow of information. ... Modulation is the process of varying a carrier signal, typically a sinusoidal signal, in order to use that signal to convey information. ... Channel, in communications (sometimes called communications channel), refers to the medium through which information is transmitted from a sender (or transmitter) to a receiver. ... The unit interval is the minimum time interval between condition changes of a data transmission signal. ... In telecommunication, serial transmission is the sequential transmission of the signal elements of a group representing a character or other entity of data. ... In telecommunication, parallel transmission is: The simultaneous transmission of the signal elements of a character or other data item. ... Modulation is the process of varying a carrier signal, typically a sinusoidal signal, in order to use that signal to convey information. ... Synchronization is coordination with respect to time. ... Look up binary in Wiktionary, the free dictionary. ... In information theory, a signal is a flow of information. ... In telecommunications and computing, bit rate (sometimes written bitrate) is the frequency at which bits are passing a given (physical or metaphorical) point. It is quantified using the bit per second (bit/s) unit. ... In telecommunication, the term modulation rate has the following meanings: 1. ... In information theory, a signal is a flow of information. ... Phase, from the Greek phasis, meaning appearance, has a number of related meanings in English. ... A telephone line (or just line) is a single-user circuit on a telephone communications system. ... A modem (a portmanteau word constructed from modulator and demodulator) is a device that modulates a carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. ... This article needs to be cleaned up to conform to a higher standard of quality. ... The term input has a variety of uses in different fields. ... // Information processing In information processing, output is the process of transmitting information by an object (verb usage). ... In telecommunications and computing, bit rate (sometimes written bitrate) is the frequency at which bits are passing a given (physical or metaphorical) point. It is quantified using the bit per second (bit/s) unit. ... In telecommunication, data transfer rate or just transfer rate is the average number of bits, characters, or blocks per unit time passing between corresponding equipment in a data transmission system. ...
