Abstract

This paper proposed the design and implementation of digital signal processing virtual lab (DSPVL) based on components. In the DSPVL, all the virtual instruments are developed as components and implemented as Java Beans, which improve the developing efficiency, the reuse of software and make the system be maintained and expanded easily. This paper also introduces the characters and architecture of user platform and illustrates the key design and implementation technologies. In the DSPVL, we developed a lot of components for the experiments in Digital Signal Processing (DSP) course. In this paper, we also gives an example of designing components of Discrete Fourier Transform (DFT) to show the process of designing, implementing and using the components in the DSPVL.
