| Definition: | unit of modulation rate in telegraphy and data communication and of line digit rate in digital transmission, equal to one second to the power minus one
1 Bd := 1 s−1
Note 1 to entry: For example, if the duration of the unit interval is 20 ms, the modulation rate is 50 Bd.
Note 2 to entry: The term “rapidité de modulation” is used in French in all cases, with the synonym “débit en ligne” in the case of digital transmission; in English the terms “modulation rate” and “line digit rate” are used in different fields.
