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 of the following are the advantages of using modulation techniques?
Following are some of the advantages for implementing modulation in the communication systems.
- Antenna size gets reduced.
- No signal mixing occurs.
- Communication range increases.
- Multiplexing of signals occur.
- Adjustments in the bandwidth is allowed.
- Reception quality improves.
What is the disadvantages of modulation?
Disadvantages of Amplitude Modulation: It is not efficient in terms of its use of bandwidth. It requires a bandwidth equal to twice that of the highest audio frequency. In amplitude modulation sidebands contain the signal. To avoid interference the actual bandwidth used by AM transmission is 10000 Hz.
What are the advantages and disadvantages of binary ASK?
One important advantage of ASK is it need lees bandwidth than FSK. Disadvantages of Amplitude-shift keying (ASK): Unfortunately, ASK is linear and sensitive to atmospheric noise, distortion, propagation condition on different routes in PSTN.It requires excessive bandwidth and is therefore a waste of power.
What is the disadvantages of ASK?
Disadvantages of ASK modulation ➨ASK modulation is very susceptible to noise interference. This is due to the fact that noise affects the amplitude.
What are the different types of modulation techniques?
Usually high frequency sine wave is used as a carrier wave signal. These modulation techniques are classified into two major types: analog and digital or pulse modulation. Prior to discussing further about the different types of modulation techniques, let us understand the importance of modulation.
What are the advantages and disadvantages of demodulation?
The main advantage is that since a coherent reference is not required for demodulation as long as 0 < u < 1, the demodulator becomes simple and inexpensive. The main disadvantage of this modulation is the wastage of carrier power. It is used in many commercial broadcast applications, it is sufficient to justify its use.
Why is modulation important in the communication system?
The following points describe modulation’s importance in the communication system. In signal transmission, the signals from various sources are transmitted through a common channel simultaneously by using multiplexers. If these signals are transmitted simultaneously with a certain bandwidth, they cause interference.
Which is advantage of digital modulation over analog modulation?
The main advantages of the digital modulation over analog modulation include permissible power, available bandwidth and high noise immunity. In digital modulation, a message signal is converted from analog to digital message, and then modulated by using a carrier wave.
