In view of such problems as insufficient experimental teaching facilities for testing technology courses, abstract concepts of digital signal acquisition and processing and the complex computation, the paper provides the virtual simulation software for signal processing with a computer. The software system mainly comprises 6 experiment modules, i.e. signal generator, sampling theorem and FFT, correlation analysis, convolution analysis, signal modulation and demodulation simulation, frequency response function and digital filter. The system is applied to experimental teaching, exhibiting a prominent effect.
