In this paper, a digital signal processing method of AFC (automatic frequency control) is proposed for a home use VCR system. The proposed method has the ability of frequency tracking of a wide range. Implemented with digital circuits, the system is to be used in a digital video system and saves the cost of a hardware compared with a conventional analog automatic frequency control method using several PLL's in case of making home use VCR systems compatible with several TV systems.
