The bit rate is the number of data bits transmitted per second (bps), so how many 0 and 1 are transmitted in one second.
Ex: 1200 bps = 1200 0 and 1 trasmitted per second.
A baud rate does not exist as a baud is already a rate.
A baud is the number of symbol change transmitted per second, so how many times it can change from 0 to 1.
Ex: 1200 bps = changes up to 1200 times from 0 to 1 in one second.
Baud is the number of times per second that a signal changes state. (Not "baud rate".) That may or may not relate to the number of bits sent. Example: You send "010101" but the circuit inverts every other bit as part of a security scheme, so you have sent six bits of data but no change of state has occurred. In actual use, "baud" usually refers to the clock rate.
