Questions tagged [baud-rate]

"baud-rate" refers to the number of signal or symbol changes that occur per unit time. This tag is for questions that get, set, or otherwise manipulate the baud rate.

In telecommunications and electronics, baud (/ˈbɔːd/, unit symbol "Bd") means symbols per second or pulses per second. A symbol being one of several voltage, frequency, or phase changes.

Thus a "baud-rate" refers to the number of signal or symbol changes that occur over time—most commonly per second. A baud rate differs from a bit-rate in that a single symbol transition (baud) can communicate more than one bit during the interval, whereas a bit rate is a single bit per interval. However, if only two symbols are defined for some system, e.g. "0" and "1", then the baud/bit rates are synonymous.

This tag is OS and Language independent, as long as there's a mechanism for manipulating the serial data rate this tag can apply.
