BAUD RATE Meaning and
Definition
-
Baud rate is a term used in telecommunications and computing to measure the rate at which data is transmitted over a communication channel. It is a unit of measurement that specifies the number of signal changes or transitions that can occur per second. Baud rate is typically expressed in bits per second (bps), where a bit represents a binary digit of data.
The baud rate indicates how quickly a device can send or receive information. It determines the data transmission speed and is a critical factor in determining the efficiency and reliability of a communication system. The higher the baud rate, the faster the data can be transferred.
Baud rate is commonly used in the context of modems, where it refers to the speed at which data is sent over a telephone line. In this application, baud rate represents the number of signal changes per second that are transmitted or received. It is important to note that baud rate and bit rate are not always the same. Baud rate only indicates the number of signal changes, while bit rate refers to the number of bits transmitted per second.
In summary, baud rate is a measurement of the data transmission speed in bits per second, indicating the number of signal changes that occur within a given time frame. It plays a crucial role in evaluating the effectiveness and speed of communication channels.

Etymology of BAUD RATE
The term "baud rate" originates from the name Jules Antoine Lissajous and his invention of the Lissajous curve. The Lissajous curve refers to the pattern created by two perpendicular sinusoidal waveforms of different frequencies. Lissajous curves were widely used in early telegraphy and transmission systems to continually adjust the transmission speed by measuring the intersection points of the curves. In the 1920s, this measurement was called "baud" in honor of Lissajous. Over time, the term "baud" was then associated specifically with the symbol rate or the number of signal changes per second in a communication system, and "baud rate" became the standard phrase to describe the data signaling rate in bits per second (bps) in various communication technologies.
