Abstract

With the information age and the advent of the digital world, digital signal processing has become an extremely important disciplines and technical fields. Current digital signal processing in communications, voice, image, automatic control, radar, military, aerospace, medical and household appliances and many other fields has been widely used. In digital signal processing plays an important role and has been widely used in digital filters (DF, Digital Filter). Digital filter is a time discrete signal is used to filter digital system, through the mathematical treatment of the sample data to achieve the frequency-domain filtering purposes.

MATLAB is in English MATrix LABoratory (Matrix Laboratory) acronym. It is the United States, MathWorks has introduced a set of computing and graphics processing for scientific visualization, high-performance language and software environment. Its signal processing toolbox contains a variety of classic and modern digital signal processing technology, is a very good algorithm research and aided design tools. In the design of digital filters, it is usually carried out using MATLAB-aided design and simulation.

The basis of intensive training will be completed a number of Chebyshev band-pass IIR filter design using bilinear transform and infinite impulse response IIR principle of the completion of design and simulation using MATLAB.

Keywords: Digital signal processing digital filters Chebyshev bilinear transform MATLAB
