In this paper, the authors compare the performance of the block linear equalizer used with the block data transmission system with that of the conventional linear transversal equalizer that is used with an uninterrupted continuous system. The result of the comparison show that the block data transmission system has some useful advantages over the continuous system like exact channel equalization is achieved in all cases and the system is free from error extension effects. The disadvantage of the block data transmission system is that for a given information rate the bandwidth required is larger as compared to the continuous systems.
