Baud Rate

maker

The number of signal changes or symbols transmitted per second in a communication channel.

expanded

Baud rate measures the number of signal units transmitted per second that can convey one or more bits of information, depending on the encoding scheme. It is crucial in digital communications to determine how fast data can be transmitted over a communication link, impacting devices such as modems and serial communication interfaces.

examples

A typical UART (Universal Asynchronous Receiver-Transmitter) module in microcontrollers can be configured with a baud rate of 9600 baud.

Used extensively in microcontroller projects for serial communication between devices such as an Arduino Uno and a computer.

A 56K modem transmits data using a baud rate of 3429 baud with each symbol carrying multiple bits.

In home internet connections via dial-up modems, where modulation schemes allow higher data rates by encoding multiple bits per symbol.
