Advantages and Disadvantages of Frequency Modulation
| Advantages | Disadvantages |
|---|---|
| Less interference and noise. | Equipment cost is higher. Has a large bandwidth. |
| Power Consumption is less as compared to AM. | More complicated receiver and transmitter |
Which is better phase or frequency modulation?
Due to higher bandwidth, frequency Modulation has a better signal-to-noise ratio (SNR) than Phase Modulation.
Which of the following is the disadvantage of the modulation?
Explanation: The disadvantage of FM over AM is that in frequency modulation large bandwidth is required. While, in case of advantages, FM is less prone to noise interference and has lower power consumption compared to AM.
What is meant by phase modulation?
Phase modulation (PM) is a modulation pattern for conditioning communication signals for transmission. It encodes a message signal as variations in the instantaneous phase of a carrier wave. Phase modulation is one of the two principal forms of angle modulation, together with frequency modulation.
What is the main advantage of using a phase modulator rather than a direct frequency modulation?
The advantages of phase modulation include the following. Phase modulation (PM) is a simple contrasted to Frequency modulation (FM). It is used to find out the velocity of a target by removing Doppler data. This needs constant carrier which is achievable during phase modulation however not in FM (frequency modulation).
What is phase modulation used for?
Phase modulation is widely used for transmitting radio waves and is an integral part of many digital transmission coding schemes that underlie a wide range of technologies like Wi-Fi, GSM and satellite television.
Which of the following is the disadvantage of AM?
Following are the disadvantages of AM: ➨The most natural as well as man made radio noise are of AM type. The AM receivers do not have any means to reject this kind of noise. ➨Weak AM signals have low magnitude compare to strong signals.
What is the main disadvantage of FM?
Disadvantages of FM: Much more Bandwidth (as much as 20 times as much). More complicated receiver and transmitter.
What is the advantage of phase modulation?
The other unique advantage of phase modulation is signal modulation where it allows for high-speed communication using a telephone system. When the data is under transmission having no intrusion, then the rate of speed can be observed. This kind of modulation is almost resilient to noise.
Why do we use phase modulation?
What is advantage of phase modulation?
The main benefit of this modulation is signal modulation because it permits computer for communicating on high-speed using a telephone system. When the information is being transmitted without intrusion then the speed rates can be observed.
What is phase modulation example?
For digital signals, phase modulation (PM) is widely used in conjunction with amplitude modulation (AM). For example, quadrature amplitude modulation (QAM) uses both phase and amplitude modulation to create different binary states for transmission (see QAM). See modulation and carrier.
