AB  - The demands are growing bigger for improving the quality of compressed digital audio as portable non-CD players become popular. Because high compression causes poor sound quality, a solution to improve it is being sought. An effective solution is to generate high frequency components from the lower one. We propose the idea of using imaging components and digital filters designed using “Sampled-Data Control” to minimize the error between an assumed original analog signal and interpolated digital signal. We successfully improved the sound quality of compressed audio by realizing the close frequency spectrum to CD especially for the sound with low bit rate.
