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.

I. Introduction

The world of science and engineering is filled with signals: images from remote space probes, voltages generated by the heart and brain, radar and sonar echoes, seismic vibrations, and countless other applications. Digital Signal Processing is the science of using computers to understand these types of data. This includes a wide variety of goals: filtering, speech recognition, image enhancement, data compression, neural networks, and much more. DSP is one of the most powerful technologies that will shape science and engineering in the twenty-first century. So doing experiments is very important in this course^[1].
