波特率是指有效数据信号调制载波的速率，即单位时间内载波调制状态变化的次数。它是对符号传输速率的一种度量，1波特即指每秒传输1个符号，而通过不同的调制方式，可以在一个码元符号上负载多个bit位信息。
Baud rate refers to the rate at which the effective data signal modulates the carrier, that is, the number of times the carrier modulation state changes in unit time. It is a measure of symbol transmission rate. 1 baud means that one symbol is transmitted per second, and multiple bit information can be loaded on a symbol by different modulation methods.

单位“波特”本身就已经是代表每秒的调制数，以“波特每秒”（Baud per second）为单位是一种常见的错误。
The unit “baud” itself represents the number of modulation per second. It is a common error to use “baud per second” as the unit.
波特率的公式
The formula of baud rate
波特（Baud，单位符号：Bd）这一单位是以法国电讯工程师让·莫里斯·埃米尔·博多（1845-1903）的姓氏来命名的，他是电传与博多式电报机的发明人，数位通信的先驱之一。
Baud (unit symbol: BD) is named after French telecommunication engineer Jean Morris Emil Bodo (1845-1903). He is the inventor of telex and Bodo Telegraph and one of the pioneers of digital communication.
波特率可以被理解为单位时间内传输符号的个数（传符号率），通过不同的调制方法可以在一个符号上负载多个比特信息。因此信息传输速率即比特率在数值上和波特率有这样的关系：I = S * log2N.其中 I 为传信率，S 为波特率，N 为每个符号负载的信息量，而 log2N 以比特为单位。
Baud rate can be understood as the number of transmitted symbols per unit time (symbol rate). Multiple bit information can be loaded on a symbol by different modulation methods. Therefore, there is a numerical relationship between the bit rate and the baud rate: I = s * log2n, where I is the transmission rate, s is the baud rate, n is the amount of information per symbol load, and log2n is in bits.
波特率与比特率的区分
The distinction between baud rate and bit rate
比特率在数字信道中，比特率是数字信号的传输速率，它用单位时间内传输的二进制代码的有效位(bit)数来表示，其单位为每秒比特数 bit/s(bps)、每秒千比特数(Kbps)或每秒兆比特数(Mbps)来表示(此处 K 和 M 分别为 1000 和 1000000，而不是涉及计算机存储器容量时的 1024 和 1048576)。
Bit rate in digital channel, bit rate is the transmission rate of digital signal. It is expressed by the number of significant bits (bits) of binary code transmitted in unit time, and its units are bits / S (BPS), kilobits per second (kbps) or megabits per second (Mbps) (where K and m are 1000 and 1000000 respectively, instead of 1024 and 1000000 when computer memory capacity is involved) 1048576)。
波特率指数据信号对载波的调制速率，它用单位时间内载波调制状态改变次数来表示，其单位为波特(Baud)。
The baud rate of the data in baud modulation.
显然，两相调制(单个调制状态对应 1 个二进制位)的比特率等于波特率；四相调制(单个调制状态对应 2 个二进制位)的比特率为波特率的两倍；八相调制(单个调制状态对应 3 个二进制位)的比特率为波特率的三倍；依次类推。
Obviously, the bit rate of two-phase modulation (a single modulation state corresponds to one binary bit) is equal to the baud rate; the bit rate of four phase modulation (one modulation state corresponds to two binary bits) is twice that of baud rate; the specific rate of eight phase modulation (single modulation state corresponding to three binary bits) is three times of baud rate; and so on.
波特率是对信号传输速率的一种度量，通常以“波特”（baud）为单位。波特率有时候会同比特率混淆，实际上后者是对信息传输速率（传信率）的度量。波特率可以被理解为单位时间内传输码元符号的个数（传符号率），通过不同的调制方法可以在一个码元上负载多个比特信息。
Baud rate is a measure of signal transmission rate, usually in baud. Baud rate is sometimes confused with bit rate, which is actually a measure of information transmission rate. Baud rate can be understood as the number of transmitted symbol symbols per unit time (symbol rate). Multiple bit information can be loaded on a symbol by different modulation methods.
调制解调器的通讯速度。波特率是指线路状态更改的次数。只有每个信号符合所传输数据的一位时，才等于每秒位数。
Communication speed of modem. The baud rate is the number of times the line state has changed. Only if each signal corresponds to one bit of the transmitted data, it is equal to bits per second.
为了在彼此之间通讯，调制解调器必须使用相同的波特率进行操作。如果将调制解调器的波特率设置为高于其他的调制解调器的波特率，则较快的调制解调器通常要改变其波特率以匹配速度较慢的调制解调器。
In order to communicate with each other, modems must operate at the same baud rate. If you set the baud rate of a modem to be higher than that of other modems, the faster modem will usually have to change its baud rate to match a slower modem.
(严格来说，波特率不在传输领域，出现传输、信道等字眼容易产生混淆，波特率描述的是单位时间内调制信号的能力，经它调制出来的信号才以比特的形式来传输，或者这样说，信号在传输过程中，如果要经过数模转换，就需要调制，那么传输时间除了消耗在其它领域外，还消耗在调制过程和在信道的传输过程，描述信号调制能力用波特率，描述信号传输能力用比特率。）
(strictly speaking, baud rate is not in the field of transmission. Words such as transmission and channel are easy to be confused. Baud rate describes the ability to modulate signals in unit time, and the signals modulated by it are transmitted in the form of bits. In other words, in the transmission process, if the signal needs to be modulated through digital to analog conversion, then the transmission time is consumed in other aspects In addition, it also consumes in the modulation process and the transmission process in the channel. The baud rate is used to describe the signal modulation capability, and the bit rate is used to describe the signal transmission capability.)
