ABSTRACT:
A storage device includes a signal processor that receives an input signal that includes a direct current (DC) voltage offset. An encoder receives the input signal from the signal processor and selectively inverts portions of the input signal based on at least one of an average DC value and a weighted DC value of the input signal.
