For this reason, the baud rate value will often be lower than the gross bit rate. Example of use and misuse of "baud rate": It is correct to write "the baud rate of my COM port is 9,600" if we mean that the bit rate is 9,600 bit/s, since there is one bit per symbol in this case. It is not correct to write "the baud rate of Ethernet is 100 ...
The ratio is not necessarily an integer; in 4B3T coding, the bit rate is 4 / 3 of the baud rate. (A typical basic rate interface with a 160 kbit/s raw data rate operates at 120 kBd.) Codes with many symbols, and thus a bit rate higher than the symbol rate, are most useful on channels such as telephone lines with a limited bandwidth but ...
UART clock; allows integer division to common baud rates (272×115200 baud or 272×96×1,200 baud). CPU frequency or multiple of it (as well as video and system master clocks) in older Apple Macintosh computers (Classic, LC, etc.).
For example, in a serial line with a baud rate of 2.5 Gbit/s, a unit interval is 1/(2.5 Gbit/s) = 0.4 ns/baud. ... Baud; Symbol rate; Frequency; Telecommunications;

Thus, the maximum fundamental frequency is reduced to one fourth of the baud rate. This makes signal transmission more amenable to copper wires. The lack of transition on a 0 bit means that for practical use, the number of consecutive 0 bits in the transmitted data must be bounded; i.e. it must be pre-coded using a run-length limited code.
The speed or bits per second of the line (equal to the Baud rate when each symbol represents one bit). Some systems use automatic speed detection, also called automatic baud rate detection. Whether to use or not use parity; Odd or even parity, if used; The number of stop bits sent must be chosen (the number sent must be at least what the ...
Signal processors, such as four-phase modems, cannot change the DSR, but the modulation rate depends on the line modulation scheme, in accordance with Note 4. For example, in a 2400 bit/s 4-phase sending modem, the signaling rate is 2400 bit/s on the serial input side, but the modulation rate is only 1200 bauds on the 4-phase output side.
