# bits per second (b/s)

**bits per second (b/s):** A unit used to express the number of bits passing a designated point per second. (188) *Note 1:* For example, for two-condition serial transmission in a single channel in which each significant condition represents a bit, *i.e.,* a 0 or a 1, the bit rate in bits per second and the baud have the same numerical value only if each bit occurs in a unit interval. In this case, the data signaling rate in bits per second is 1/T, where T is the unit interval. *Note 2:* The abbreviation *"bps"* is not in accordance with international standards, and is therefore deprecated.
