Abstract

An approaching source of sound shows a higher frequency than a stationary sound, and a receding source shows a lower frequency. This change in the observed frequency of the sound, due to the motion of the source, is a consequence of the wave nature of sound and this phenomenon is called the “Doppler Effect." The change in the observed frequency is called the “Doppler shift." This paper discusses the simulation of Doppler Shift using MATLAB and demonstrates the process of frequency broadening implementing hardware.
