Doppler effect

Abstract

Doppler Effect is the change in frequency of a sound causes by the movement of the source producing the sound. The distance, velocity of the source movement and speed of sound in medium determines the how the frequency changes.Doppler shift can be reproduced using programming languages like "Matlab". But usually the reproduction quality of the Doppler shift which is produced using the programming language is not anything similar to the Doppler shift experienced in the real life. This is mainly because there are number factors which are ignored while programming the Doppler shift reproduction program. This review focuses on how to reproduce virtual moving source causing Doppler shift more accurately as heard in the natural world.
