The blended word for modulation and demodulation is "modem." A modem is a device that modulates digital signals into analog signals for transmission and demodulates received signals back into digital form. This process enables communication over various types of networks, such as telephone lines and broadband connections.
It is used for the radio control of model aircraft,boats, cars.
Demodulation is the process of extracting the original information from a modulated carrier wave. The primary needs for demodulation include a clear understanding of the modulation scheme used, a receiver capable of accurately processing the incoming signal, and synchronization to ensure the timing of recovery aligns with the original signal. Additionally, effective noise filtering is crucial to enhance the quality of the demodulated output and minimize interference.
Phase-Locked Loops (PLLs) are used in Amplitude Modulation (AM) and Frequency Modulation (FM) for various purposes, including frequency synthesis and demodulation. In FM, PLLs can effectively track the frequency variations of the modulated signal, enabling accurate demodulation by locking onto the instantaneous frequency. In AM, PLLs can help improve the signal quality and stability by maintaining a consistent carrier frequency, which is essential for effective signal recovery and minimizing distortion. Overall, PLLs enhance the performance and reliability of both AM and FM systems.
Single side band suppressed carrier modulation is like amplitude modulation except that one of the sidebands is suppressed or filtered out. Each sideband carries the same though opposite, information, so suppressing the one sideband allows more power to be placed into the one remaining sideband. The downside, of course, is that the demodulation process is more complex.
Phase modultion is one of the three ways of modulating or altering a signal so that it is able to carry information. The other two are amplitude and frequency modulation. Phase modulation is used in high speed modems.

its nothing but modulation and demodulation. modulation of the message is done in transmitter side and demodulation is done at receiver side and retrieving the original message.

Function Of Modem Is Modulation And Demodulation
Function Of Modem Is Modulation And Demodulation
The word "modem" comes from the contracting of the two wordsmodulator, and demodulator.MOdulation DEModulation
MODEM modulation & demodulation .......
Demodulation is needed with modulation becoz modulation it is converting analog to digital signal n we can't understand digital. That's why we require digital to analog converter or demodulator.
