Digital Filler Design Using Matlab

Abstract

Signals from the sender to the receiver or within the devices are subject to noise due to electromagnetic waves between the signals or because of climate change and other reasons. This noise affects the original signal, leading to a change in the shape and characteristics, therefore to get rid of this noise would be by using the filters. The filter is the most important system used in different devices and applications, since the primary purpose of the filters is to get rid of the unwanted signal noise This research focuses on digital filters. There are generally two types: FIR & IIR, but the basic idea are based on FIR. This research contains some of the concepts of the language MATLAB. The main objective of this research is to design a moving average filter for filtering the voice, using the software program which is written by the programming language MATLAB.
