The
baud rate is a measurement for describing the modulation rate of the data transfer rate. Often the baud rate is designated as symbol rate, modulation rate or symbol speed.
The baud rate describes the number of signal codes (symbol) that can be transferred per second. Each signal code corresponds to a defined measurable signal modification in the physical transmission medium. If the medium is electrical, the speed of the measured signal modification often corresponds to the frequency. The number of symbols is measured. The baud rate's unit is baud (abbreviation: Bd).
The baud rate is often mixed up with the
Bit rate, measured in Bit/s (German) or
bps (English). These measured figures are identical only, if one symbol - coding exactly one bit - per step is transferred. In case of many modulations several bits per symbol are transferred.
