Method and apparatus for restoring signal using minimum value sampling

摘要

Provided is an apparatus and method to restore a signal using minimum value sampling, more particularly, a signal restoring apparatus and method using minimum value sampling, which are capable of effectively preventing deterioration of a restored signal caused by aliasing occurring when minimum value sampling of an input signal is performed in order to restore a signal. The apparatus to restore a signal using the minimum value sampling includes a storage unit to store a sample value obtained through the minimum value sampling of an input signal in a predetermined sampling interval; a position determination unit to determine the position of the sample value in the sampling interval; and a restoration unit to restore the input signal using the stored sample value with respect to the determined position.
