MATLAB is released by the United States mathworks mainly for scientific
computing, visualization and interactive program designed high-tech computing
environment. It numerical analysis, matrix computation, scientific data visualization
as well as non-linear dynamic systems modeling and simulation, and many other
powerful integrated in an easy-to-use Windows environment, scientific research,
engineering design and the need for effective numerical the edit mode many scientific
fields provides a comprehensive solution, and in large part to get rid of the traditional
non-interactive programming language (such as C, Fortran), on behalf of the advanced
level of today's international scientific computing software.
This article describes how to use MATLAB simulation software systems and
digital signal processing learned knowledge using frequency sampling method to
design a digital high-pass filter. In order to consolidate the theoretical classroom
learning, and basic questions and explain basic signal processing phenomenon can be
learned theoretical knowledge to correctly analyze the signal processing.
