Introduction
This project is undertaken with the
objective of demonstrating the design process of a digital filter using the
windowing method in conjunction with the Kaiser window to fit given
requirements. The filter is then analyzed and verified. A comprehensive summery
of the basic principles of filter design also have been revised as a part of
this project report. Mathematical analysis has been carried out using Matlab
2014a software. It is submitted as the semester project for the module 'Digital Signal Processing'.
