采样率转换程序，程序主体分为上采样与下采样-Sample rate conversion process, the program is divided into the main sampling and down-sampling

有关多采样率转换问题，本文介绍了多采采样率转换的MATLAB实现和基础理论。 -This article describes a much more expensive than the sample rate conversion of MATLAB and basic theory of the multi-sampling rate conversion problem.
