# symbol rate (SR)

The symbol rate is a characteristic value of digitaltransmission systems. It indicates the number of symbols that can be transmitted in a unit of time. The commonly used time unit is the second. Accordingly, the symbol rate is the quotient of symbols per second (S/s) or baud per second (Bd/s), since one baud corresponds to one symbol. The relationship between the symbol rate and the bit rate is possible via the number of bits that make up the symbols.
