  2. Symbol rate - Wikipedia

    en.wikipedia.org/wiki/Symbol_rate

    It is not correct to write "the baud rate of Ethernet is 100 megabaud" or "the baud rate of my modem is 56,000" if we mean bit rate. See below for more details on these techniques. The difference between baud (or signaling rate) and the data rate (or bit rate) is like a man using a single semaphore flag who can move his arm to a new position ...

  3. Baud - Wikipedia

    en.wikipedia.org/wiki/Baud

    The ratio is not necessarily an integer; in 4B3T coding, the bit rate is ⁠ 4 / 3 ⁠ of the baud rate. (A typical basic rate interface with a 160 kbit/s raw data rate operates at 120 kBd.) Codes with many symbols, and thus a bit rate higher than the symbol rate, are most useful on channels such as telephone lines with a limited bandwidth but ...

  4. List of interface bit rates - Wikipedia

    en.wikipedia.org/wiki/List_of_interface_bit_rates

    This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications networks.

  5. Bandwidth (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Bandwidth_(signal_processing)

    In the context of, for example, the sampling theorem and Nyquist sampling rate, bandwidth typically refers to baseband bandwidth. In the context of Nyquist symbol rate or Shannon-Hartley channel capacity for communication systems it refers to passband bandwidth. The Rayleigh bandwidth of a simple radar pulse is defined as the inverse of its ...

  6. Shannon–Hartley theorem - Wikipedia

    en.wikipedia.org/wiki/Shannon–Hartley_theorem

    where is the pulse rate, also known as the symbol rate, in symbols/second or baud. Hartley then combined the above quantification with Nyquist's observation that the number of independent pulses that could be put through a channel of bandwidth B {\displaystyle B} hertz was 2 B {\displaystyle 2B} pulses per second, to arrive at his quantitative ...

  7. Channel capacity - Wikipedia

    en.wikipedia.org/wiki/Channel_capacity

    The bandwidth-limited regime and power-limited regime are illustrated in the figure. ... Thus, it is possible to achieve a reliable rate of communication of ...

  8. Spectral efficiency - Wikipedia

    en.wikipedia.org/wiki/Spectral_efficiency

    Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the medium access control (the channel ...

  9. Bit rate - Wikipedia

    en.wikipedia.org/wiki/Bit_rate

    In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. [1]The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s).
