  2. Symbol rate - Wikipedia

    en.wikipedia.org/wiki/Symbol_rate

    The symbol rate is measured in baud (Bd) or symbols per second. In the case of a line code, the symbol rate is the pulse rate in pulses per second. Each symbol can represent or convey one or several bits of data. The symbol rate is related to the gross bit rate, expressed in bits per second.

  3. Baud - Wikipedia

    en.wikipedia.org/wiki/Baud

    It is the unit for symbol rate or modulation rate in symbols per second or pulses per second. It is the number of distinct symbol changes (signalling events) made to the transmission medium per second in a digitally modulated signal or a bd rate line code. Baud is related to gross bit rate, which can be expressed in bits per second (bit/s). [1]

  4. Serial port - Wikipedia

    en.wikipedia.org/wiki/Serial_port

    The speed (or baud rate) includes bits for framing (stop bits, parity, etc.), thus the effective data rate is lower than the baud rate. For 8-N-1 encoding, only 80% of the bits are available for data (for every eight bits of data, ten bits are sent over the serial link — one start bit, the eight data bits, and the one stop bit).

  5. Data-rate units - Wikipedia

    en.wikipedia.org/wiki/Data-rate_units

    The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...

  6. Data rate - Wikipedia

    en.wikipedia.org/wiki/Data_rate

    Bit rate, the number of bits that are conveyed or processed per unit of time . Data signaling rate or gross bit rate, a bit rate that includes protocol overhead; Symbol rate or baud rate, the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time

  7. Asynchronous serial communication - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_serial...

    The speed or bits per second of the line (equal to the Baud rate when each symbol represents one bit). Some systems use automatic speed detection, also called automatic baud rate detection. Whether to use or not use parity; Odd or even parity, if used; The number of stop bits sent must be chosen (the number sent must be at least what the ...

  8. Shannon–Hartley theorem - Wikipedia

    en.wikipedia.org/wiki/Shannon–Hartley_theorem

    By taking information per pulse in bit/pulse to be the base-2-logarithm of the number of distinct messages M that could be sent, Hartley [3] constructed a measure of the line rate R as: = ⁡ (), where is the pulse rate, also known as the symbol rate, in symbols/second or baud.

  9. Modulation - Wikipedia

    en.wikipedia.org/wiki/Modulation

    If the symbol rate (also known as the baud rate) is symbols/second (or baud), the data rate is bit/second. For example, with an alphabet consisting of 16 alternative symbols, each symbol represents 4 bits. Thus, the data rate is four times the baud rate.
