Abstract: Disclosed is an interpolation filter based on time assignment algorithm. An interpolation filter comprises an enable signal generating part generating enable signals for operation of the interpolation filter, an input value generating part generating input values, a first calculating part generating a first output value based on a first enable signal and a first input value, a second calculating part generating a second output value based on a second enable signal and a second input value, and an output value selecting part selecting a final output value among the first output value and the second output value. Thus, continuity of output data can be guaranteed, and hardware can be shared by using time assignment algorithm so that a total size of the interpolation filter can be reduced.
