Line 30:

Linear block codes, have the property of [[linearity]], i.e the sum of any two codewords is also a code word; and they are applied to the source bits in blocks; hence the name linear block codes. There are block codes that are not linear, but it is difficult to prove that a code is a good one without this property.

Any linear block code, is represented atas <math>(n,km,d_{min})</math> where

# n , is the length of the codeword, in symbols,

# km , is the number of source symbols that will be used for encoding at once,

# <math>d_{min}</math>, is the minimum hamming distance for the code
