Abstract: PURPOSE: A digital up down conversion device embodying decimation filter and interpolation filter by using IIR filter of low processing delay time and a method thereof are provided to guarantee stability and obtain phase response characteristic, thereby reducing delay time in digital up/down converting procedure. CONSTITUTION: A size response unit(520) is realized by a size response IIR(Infinite Impulse Response) filter. The size response unit determines the coefficient of the size response IIR(Infinite Impulse Response) filter by using size response characteristic of a traditional FIR filter. A phase compensation unit(530) is composed with phase compensation IIR filter based on full band pass. The phase compensation unit revises non-linear phase of an output signal of the size response unit.
