Abstract
A Viterbi detector for extending tolerable extent of DC bias is disclosed. By adding a fixed value to a reference level or subtracting a fixed value from the reference level, the tolerable extent of the DC bias of the input signal is increased. According to the invention, this effect can be achieved with a control circuit and the tolerable extent of the DC bias can be increased by about 100% as compared with the tolerable extent of the DC bias in the conventional approaches.
