In this paper, we propose a new method for Active Net model. Active Net is a lattice network model that is based on minimizing an energy to extract the region of a target object. In a conventional method, only one target is used by one net. Therefore

In this paper, we propose a digital signal processing type frequency locked loop (DSP-FLL) using a frequency difference detector (FDD). Since the DSP-FLL is controlled by the frequency, the pole of the voltage controlled oscillator vanishes in the ba
