The required bandwidth is related to bit rate and the modulation order M. It is so that the double sided bandwidth w = symbol rate= bit rate rb/ divided by the number of bit per symbol n . The number of bits per symbol is = log 2M with M is the M is the QAM modulation order.

In digital television transmission the symbol rate calculation is: symbol rate in symbols per second = (Data rate in bits per second × 204) / (188 × bits per symbol)
