Continuous Wave Modulation- Amplitude Modulation (AM), Frequency Modulation (FM) & Phase Modulation

The concept of Continuous Wave Modulation has been explained here. Amplitude Modulation (AM), Frequency Modulation (FM) and Phase Modulation (PM) come under the category of Continuous Wave Modulation. Here we will discuss, what is modulation and different types of modulation. So let's first see the definition of modulation and it's classification - Definition of Modulation Modulation is a process by which some characteristic (amplitude/frequency or phase) of a high frequency carrier wave is varied in accordance with the instantaneous value of the message signal (modulating signal). Now we will see the classification of modulation- Types of Modulation Types of Modulation, classification of modulation Modulation can be classified broadly into two types - *Continuous wave modulation *Pulse modulation Continuous Wave Modulation In this type of modulation the carrier wave is continuous. Continuous wave modulation is a technique of modulation where some parameter (amplitude, frequency or phase) of a sinusoidal carrier is varied in accordance with the instantaneous value of the modulating signal. The continuous wave modulation can again be classified into two types- *Amplitude Modulation (AM) *Angle Modulation Amplitude Modulation Message Signal and the Carrier Wave, modulating signal and the carrier signal Message Signal and the Carrier Wave Amplitude Modulated Wave (AM Signal) Amplitude Modulated Wave (AM Signal) In amplitude modulation the amplitude of the carrier wave is varied according to the instantaneous value of the modulating (message) signal. Therefore the information is present in the amplitude variations of the carrier wave. Angle Modulation It may be defined as the process in which the total phase angle of a carrier wave is varied in accordance with the instantaneous value of the modulating signal. The Angle modulation is again of two types- *Frequency Modulation (FM) *Phase Modulation (PM) Frequency Modulation Frequency Modulation (FM) In frequency modulation, the frequency of the carrier wave is varied in accordance with the instantaneous value of the modulating signal. Phase Modulation (PM) In Phase modulation, the phase of the carrier wave is varied according to the instantaneous value of the modulating signal (message signal).
