摘要：The efficiency of the traditional DDFS is greatly depends on the large size of memory. The ROM less architecture for generating sine wave and its necessary corrective measure based on parabola has already been developed. This paper proposes a modified parabola by adding a triangular wave to achieve a sine wave with less distortion. This architecture gives better performance.
