baud

A unit of signaling speed equal to the number of discrete conditions or signal events per second. (Ref. ANSI X3.172.)

NOTE For example, one baud equals one bit per second in a train of binary signals or one 3‑bit value per second in a train of signals each of which can assume one of eight (23) different states.
