摘要： Disclosed is a digital filter having phase-adjustment ability, and more particularly to a digital filter system which can restore the phase of data transmitted via digital radio communication and thereby enhances the noise-immunity of data and the correct bit decision. The digital filter mainly includes a hold back data unit, a digital filter unit, and a signal phase modify unit to remove noises in the signals and to modify and restore correct digital wave-form signals. The digital filter having phase-adjustment ability is suitable for use in digital radio phones, pagers, etc. commonly found in the radio communication systems.
