A unit of signaling speed equivalent to the number of discrete conditions or siganl elements per second. Multiple bits can be used to characterize individual parameters within one baud; for example, 9600 bits per second at a rate of 2400 baud = 4 bits per baud. Even though it may not be true in every case, most of the time people express baud rate in bits per second.
