Reform of the Practice Links of Digital Signal Processing Based on the Idea of Hierarchical Teaching

In this paper, the defaults of present practiced links of the Digital signal process are discussed firstly. According to the teaching DSP experience for many years, the authors present the series of reforming are apply to the test and Curricula design. Based on the ideas of Hierarchical teaching, the practiced links of the DSP divided into 3 levels: in the basic part, we assign six test which are completed in class, In the second level, we design 6 comprehensiveness projects oriented practice application; Finally to keep up with the newest development of comprehensiveness DSP, we introduced the design methods using DSP toolbox of in matlab we can design all kinds of filters in DSP toolbox easily and we can convert the result into the C language and VHDL language, thus can be implement using DSP device or Field programmed gate array.
