Digital Signal Processing(DSP)is an important course for students in the current electronic information field,and its experi-ments are an important way to understand and consolidate the theory.However,most of the current experiments use large and inconvenient lab boxes,which restrict students to do experiments in the laboratory,and the portability and ease of use are not high.In response to this need,a portable"DSP Pocket Experiment Box"is designed.The kit integrates two analog signal generators and mixing units,a high-speed high-precision ADC sampling unit,a TMS320VC5509A processor,an emulator and other modules.The software part has the relevant algo-rithm experiments for DSP courses.The designed experiment box is small in size and easy to operate,which is convenient for students to carry out experiments in the dormitory.The design is of high significance to facilitate undergraduate DSP experimental teaching and moti-vate students to study in depth.
