Baud is the unit of symbol rate which also known as baud or modulation rate. Named after the French engineer Jean-Maurice-Emile Baudot, who had been the primary applied to gauge the pace of telegraph signals.

A baud or baud rate may be the quantity of frequencies or currents created per minute on the point.

In digital systems (i.e., using discrete/discontinuous values) with binary code, 1 Bd = 1 bit/s. By contrast, non-digital (or analog) systems use a continuous range of values to represent information and in these systems the exact informational size of 1 Bd varies.
