dc.description.abstract | 다양한 디지털 오디오 기기들은 흔히 서로 다른 주파수로 샘플링된 데이터를 사용하며, 자주 샘플링 주파수 변환이 필요하다. 본 연구에서는, 이 중에서 48KHz에서 44.1KHz로의 샘플링 주파수 변환과 같이 비정수배 변환에 쓰이는 Sample Rate Converter(SRC)를 간단한 구조를 갖도록 설계하였다. 또한 오버 샘플링이 SNR에 미치는 영향을 실험적으로 분석하여 좋은 SNR 을 위해서 오버 샘플링이 유용함을 입증하였다. Many sampling rates are used for various digital audio devices and sampling rate conversion is frequently needed. In this research, an optimized structure for the non-integer ratio audio sampling rate conversion from 48KHz to 44.1KHz are designed. Furthermore the effect of over-sampling to SNR is experimentally analyzed. Oddddversampling is shown to be useful to achieve good SNR. | - |
