WebThe symbol for the binary digit is either "bit" as per the IEC 80000-13 :2008 standard, or the lowercase character "b", as per the IEEE 1541-2002 standard. Use of the latter may create confusion with the capital "B" which is used for the byte. History [ edit] WebThe bits per symbol is the (modulation's power of 2) × (Forward Error Correction). So for example, in 64-QAM modulation 64 = 2 6 so the bits per symbol is 6. The Forward Error Correction (FEC) is usually expressed as a fraction; i.e., 1/2, 3/4, etc.
