| Summary: | This work is concerned with the design of digital bandpass FIR filter using
three differents method; Window, Optimal and Frequency sampling. Besides, the
filter will be designed using MATLAB Version 6.5.1 that available in the School of
Electrical and Electronic, Engineering. The project then will compare the merit and
de-merit of each method. The project also has a simple step-by-step guide for
designing bandpass FIR digital filter. From the given specification, we will calculate
the appropriate parameters that will be used in MATLAB programming. Basically,
there are five steps involve in designing digital filter such as specification of the filter
requirements, calculation of suitable filter coefficients, performs the suitable
realization structure for the filter, analysis the effects of finite wordlength on the filter
performance and implementation in software and/ or hardware. It has been found that
the Optimal method of this design of FIR digital filter provides the best result as it
produces filter which meet the specification with the least number of coefficient. The
suitable filter realization will be used is transversal filter that is the most widely using
in implementation of the digital filter. |
