Named after the French engineer Jean-Maurice-Emile Baudot, the first person to measure the speed of telegraph transmissions. Today, a Baud or Baudrate is the number of frequencies or voltages made per second on a line.
Common examples of Baudrate settings used today are 9600, 19200, 57600, and 115200.
Scales of baud
A baud can be scaled using the standard metric prefixes, as shown below.
- 1 kBd (kilobaud) = 1000 Bd
- 1 MBd (megabaud) = 1000 kBd
- 1 GBd (gigabaud) = 1000 MBd
