Abstract
This paper proposes minimum phase filter design and its applications. Which the properties of the minimum phase filter have the poles and zeros inside unit circle. The design step of the minimum phase filter, design the analog low-pass filter as reconstructions filter or output filter for digital signal processing system. The reconstruction filter is used as smoothing function for the output signal utilizing approximate derivative method and inverse transformation. The results show that the proposed method can be used to compensate attenuation of the output amplitude obtained from the reconstruction filter (for high frequency of digital signal processing system).
