Disadvantages of Frequency Modulation
Following are some of the disadvantages of Frequency Modulation
- Transmitter and Receiver should be in same channel .
- Not suitable for large distance coverage .
- Require wide range of frequency .
- It is costly .
Angle Modulation
Modulation is a process in which a low-frequency message signal is combined or imposed with a high-frequency carrier signal. It can also be defined as the process through which a message or baseband signal is transmitted with the help of a carrier signal to the receiver end. It enhances the signal strength and helps to transmit signal for a large distance range. It also helps to reduce the size of the antenna. Modulation can be Digital modulation or Analog modulation. There are various types of modulation that change the properties of carrier waves. Modulation can be Amplitude Modulation or Angle Modulation.
In Amplitude Modulation, the amplitude of the carrier signal is changed or modulated with the message signal While the angle that has phase and frequency are constant. In Angle Modulation angle that is, the phase and frequency of the carrier signal are changed or modulated with respect to the message signal, and the amplitude is kept constant.
In this article, we will get to know about Angle Modulation, Types of Angle Modulation, the Relation between FM and PM, Advantages and Disadvantages of Phase and Frequency Modulation, and its application.
