48kHz～44.1kHz抽样率转换系统设计

48 kHz to 44.1 kHz Sample Rate Conversion System

文章设计了一个最小单元的48kHz～44.1kHz抽样率转换系统.作为低通滤波器,分析和比较了无限脉冲响应滤波器(IIR)和有限脉冲响应(FIR)滤波器的特性和优缺点.根据设计要求和平面图,预计了面积和关键路径,并对后续研究提出了重点和方向.

The paper designs a minimum area 48KHz to 44.1KHz sample rate conversion system. As a low-pass filter design, the features, the advantages and the disadvantages of both FIR and IIR are analyzed and compared. The area and the critical path are also estimated according to the design and the plane figure. Finally, some key points and the design direction in the future research are put forward.
