Why Do We Experience Doppler Effect

When the source and observer are moving relative to each other, the frequency observed by the observer (fa) is different from the actual frequency produced by the source (f0). This is the definition of the Doppler effect in Physics. Here, when the source of waves is moving towards the observer, they will have an upward […]

Trade winds

Wind blowing westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone is known as the trade wind (ITCZ). Over the oceans, it is stronger and more persistent than over land, resulting in mostly cloudy skies with shallow cumulus clouds or bright skies, which make trade-wind islands popular tourist destinations.

Thunderstorms Cyclone Causes

Whenever the temperature of the Earth’s surface rises, it creates a powerful upward wind, which carries water droplets aloft, in which they freeze and fall again. The rapid movement of falling water droplets and rising air causes lightning and sound to be produced. This is referred to as a thunderstorm. It is especially common in

Special cases of the Doppler effect

The Doppler effect is a fascinating phenomenon that is observed in the propagation of waves. It deals with the apparent distortion that happens in the propagation of waves when the source or the observer of the wave are in relative motion.    According to the Doppler effect, the frequency of the wave has an apparent

Pulse Amplitude Modulation

As the name implies, Pulse Amplitude Modulation (PAM) is an analogue modulation scheme in which the amplitude of the pulse carrier fluctuates in accordance with the current amplitude of the message signal. The amplitude of the original signal will be followed by the amplitude of the pulse amplitude modulated signal as the signal traces out

Overlapping of Signals

The programming or numeric computing platform analyses the signals and indicates the algorithms based on the overlapping signals. Overlapping of signals is mainly caused due to three factors:  Formation of the propagation. Numerous targets. Compound physical effects of the propagation path. The issue of overlapping signals takes place in each frequency domain and time. Time

Limitations Of Doppler Effect

What Is the Doppler Effect? Christian Doppler, an Austrian physicist, first propagated the Doppler effect. He found that fluctuations between the source and detecting participants affect the frequency of light and sound.  In physics, the doppler effect stands to explain all kinds of waves. According to this effect, the frequency of waves, such as sound
