Design and Implementation of Digital Signal Processing Soft Laboratory

Digital signal processing (DSP) experiments plays an important role in digital signal teaching. The traditional hardware circuits are lack of flexibility and real-time. So make use of the software programming technology to construct virtual laboratory which can make up for the lacks of equipment, funds and hardware. In this paper, virtual laboratory is designed by VC ++ and MATLAB mixed programming, Call MATLAB engine to solve the VC + + and MATLAB mixed programming, The "digital signal processing" soft laboratory is realized.
