Applications of Doppler effects

We are very familiar with Doppler effect, but do you know were it is used?

The Doppler effect is observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching and an apparent downward shift in frequency for observers from whom the source is receding.

The Doppler effect can be observed for any type of wave - water wave, sound wave, light wave, etc. We are most familiar with the Doppler effect because of our experiences with sound waves. Perhaps you recall an instance in which a police car or emergency vehicle was traveling towards you on the highway. As the car approached with its siren blasting, the pitch of the siren sound (a measure of the siren's frequency) was high; and then suddenly after the car passed by, the pitch of the siren sound was low. That was the Doppler effect - an apparent shift in frequency for a sound wave produced by a moving source.

The Doppler effect is used in many technologies that benefit people. But it can have a negative impact, as well. For example, sonic booms, which are caused by supersonic aircraft, can cause objectionable sounds and vibrations on the ground, which is why supersonic airplanes are not allowed to fly over populated areas. Sonic booms are directly related to the Doppler effect. They occur when airplanes, flying at the speed of sound or higher, actually fly faster than the sound waves they are producing. All of the waves bunch up behind the craft, in an extremely small space. When the bunched-up waves reach an observer, they are "heard" all at once -- as a resounding boom.

The Air Force and NASA are experimenting with several inventions that help mitigate sonic booms. One such invention is a spike extending from the nose of the airplane. This spike essentially lengthens the plane and distributes the waves over a greater distance. This reduces the boom experienced by an observer on the ground.

Digital Signal Modulations

In general modulation is defined as a process of varying one or more properties of a signal that carries information. We basically have two types of signals,ie analog signals and digital signals.
Analog Signals are continuous time varying signals where as digital signals are discrete time signals.
fig: Analog and digital signals
In olden days Analog signals were used in for transmitting information from one place to another.But it has many disadvantages like information loss and high noise while transmitting, even after demodulation the complete transmitted information could not be retrieved. So there has been a shit from analog to digital signals. with digital signals there are many advantages and because of this we see all our electronic devices relay only on digital signals and not on analog.

The digital signals are transmitted using various modulation techniques according to the requirements.In modulation the major components are Signal that carries information, modulator,transmitting medium  and demodulator.

Common modulation methods are:
  • Amplitude modulation (AM), in which the height (i.e., the strength or intensity) of the signal carrier is varied to represent the data being added to the signal.
  • Frequency modulation (FM), in which the frequency of the carrier waveform is varied to reflect the frequency of the data.
  • Phase modulation (PM), in which the frequency of the carrier waveform is varied to reflect changes in the frequency of the data (similar but not the same as FM).
  • Polarization modulation, in which the angle of rotation of an optical carrier signal is varied to reflect transmitted data.
  • Pulse-code modulation in which an analog signal is sampled to derive a data stream that is used to modulate a digital carrier signal.
The main aim of modulation today is to squeeze as much data into the least amount of spectrum possible. That objective, known as spectral efficiency, measures how quickly data can be transmitted in an assigned bandwidth. The unit of measurement is bits per second per Hz (b/s/Hz). Multiple techniques have emerged to achieve and improve spectral efficiency.
