![]() ![]() However, reducing the baud rate of a modem may also reduce the maximum data transmission rate.īaud rates above 8000 are not very reliable on analog telephone lines, which is why most modems do not offer higher baud settings. This can be useful if a dial-up ISP requires a specific baud rate for communication. However, many dial-up modems allow you to override the default baud setting and manually enter the baud rate using a software interface. Modems typically select the most efficient baud rate automatically (sometimes called the "autobaud" setting). ![]() This means they send seven bits per signal transition, since 7 x 8000 = 56,000. 56K modems often use a baud rate of 8000. Therefore, it would only require a baud rate of 2100 (28,800 / 9). For example, a 28.8 Kbps modem may send nine bits per second. However, most modems transfer multiple bits per signal transition. If a modem transfers a single bit per electronic pulse, one baud would be equal to one bit per second ( bps). While the term was originally used to measure the rate of electronic pulses, it has also become a way to measure data transmission speeds of dial-up modems. For example, if a signal changes (or could change) 1200 times in one second, it would be measured at 1200 baud. So are there any areas where Baud rate is still the primary means of measurement, or is it pretty much just entirely a thing of the past? It kinds of sounds like it might not even be able to keep up with the internet speeds that most people use today.Baud, or baud rate, is used to describe the maximum oscillation rate of an electronic signal. ![]() For example, a fax machine can still be set to various baud rates. Telephone workers may still use it to discuss phone wire, and it is still used when discussing fax machines. In more advanced modems and data transmission techniques, a symbol may have more than two states, so it may represent more than one bit (a bit (binary digit) always represents one of exactly two states).Īctually though it is not used commonly by the everyday computer user, it is still used by those who are in the business of working with computers, as well as some other office equipment. The term baud rate has sometimes incorrectly been used to mean bit rate, since these rates are the same in old modems as well as in the simplest digital communication links using only one bit per symbol, such that binary "0" is represented by one symbol, and binary "1" by another symbol. The symbol rate is related to but should not be confused with gross bit rate expressed in bit/s. It kind of sounds like it might not even be able to keep up with the internet. ![]()
