Abstract
A decoder for detecting data within an input signal with attenuated low frequency components that comprises a Viterbi decoder, is disclosed. Viterbi decoder internal data is used along with its output bits to reduce delay between the restored direct current (DC) component and the input signal to zero. As a result, increased accuracy of DC restoration and corresponding bit error rate reduction are achieved.
