Applications of Demodulation
- Radar System: The demodulation technique is used in the radar system to extract information about range, velocity, angle, and many more. It helps in navigation, weather monitoring, and defense.
- Television: The demodulation technique is used to recover the video and audio signals which helps in proper displaying of the television programs.
- Radio broadcasting: Demodulation is used to extract the audio signals which is to be broadcast. It can retrieve AM and FM signals to broadcast over a wide range of frequency spectra.
- Underwater communication: For underwater communication, acoustic signals are used. These acoustic signals needed to be demodulated, to receive the original information coming from the deep sea.
- Medical: The demodulation technique is used to generate the image of internal organs. It is widely used in MRI and ultrasound.
What is Demodulation ?
The modulation is the technique by which data is converted into electrical or digital signals for transferring that signal over a medium. Signal modulation is done to carry the signal over large distances. After the signal transmission, the modulated signal must be converted back into the original signal to retrieve the original information.
This back-conversion is done with the help of various demodulation techniques. Hence, it means the separation of the signal from the modulated carrier. In this article, we will study these techniques in detail, their applications, advantages and disadvantages, etc.
