| Most people use baud to describe modem speeds in bits per second–but they are wrong. They may say a 9,600-bps modem transmits at 9,600 baud, but really baud is a measure of how frequently sound changes on a phone line. Modern modems transmit more bits with fewer changes in sound, so baud and bps numbers are not equal. However, only editors, pedants, and communications engineers now care about the distinction. But if you run into members of these groups, use bps instead of baud.\\ | Baud in communications refers to changes per second. In the very early days of MODEMs, for example, each bit sent equaled a single change, so baud equaled bits per second (BPS). The terms were initially interchangable. As newer modulation methods (the way the signal is sent or encoded) came along a baud represented more than one bit per second. For example a single baud may have represented two, three or four bits for each change. From that point forward, baud and BPS were no longer the same, though many people still use them interchangably. For the sake of clarity, use BPS to represent the number of bits sent per second. |
