On the basis of the soft radio, this paper analyzes the sampling frequencytransform for single series and the series, and compares them.
现以软件无线电的基本知识为基础，分析了单级和多级抽样频率转换，并进行了比较。

The part of hardware refers to CPU and CPU interface circuit, motor driving circuit, voltage-frequencytransform circuit, pulse power and so on.
硬件部分主要涉及CPU及其接口电路、电机驱动电路、变频取样电路、脉冲电源等。

When we say "frequencytransform" or talk about "representing frequency" we are usually talking about the Fourier transform, implemented as the DFT, or discrete Fourier transform.
