Abstract

The core of digital signal processing is the design of digital filter. At present, most digital filters are designed by Matlab, which is a high-performance numerical calculation software and provides a powerful function of graphical display. Matlab is widely used in engineering calculation, numerical analysis and other fields, but it is less able to develop interface. In this paper, a method of hybrid programming with VB and Matlab is introduced to design digital filter. The integrated software can take full advantages of VB and Matlab, and the process of realization indicates that this method is simple and convenient.
