Editing Baud (section)

==Definitions==
The symbol duration time, also known as the [[unit interval (data transmission)|unit interval]], can be directly measured as the time between transitions by looking at an [[eye diagram]] of the signal on an [[oscilloscope]]. The symbol duration time ''T''<sub>s</sub> can be calculated as:

:<math> T_\text{s}  =  {1 \over f_\text{s}}, </math>

where ''f''<sub>s</sub> is the symbol rate.
There is also a chance of miscommunication which leads to ambiguity.

:Example: Communication at the baud rate ''1000&nbsp;Bd'' means communication by means of sending ''1000&nbsp;symbols per second''. In the case of a [[modem]], this corresponds to ''1000&nbsp;tones per second''; similarly, in the case of a line code, this corresponds to ''1000&nbsp;pulses per second''. The symbol duration time is ''{{sfrac|1|1000}}&nbsp;second'' (that&nbsp;is, ''1&nbsp;millisecond'').

The baud is scaled using standard [[metric prefix]]es, so that for example
*1 kBd (kilobaud) = 1000 Bd
*1 MBd (megabaud) = 1000 kBd
*1 GBd (gigabaud) = 1000 MBd
