What is Amplitude Modulation:Advantages and Disadvantages.
Modulation is a process of varying one or more periodic waveform properties with a modulating signal that typically contains the data to be transmitted. Most of the radio systems in the 20 th century either used amplitude modulation or frequency modulation for radio broadcasting.
Modulation is the act or process of giving a wave or signal the amplitude or frequency of another wave or signal. In telecommunications, modulation is the process of conveying a message signal, for example a digital bit stream or an analog audio signal, inside another signal that can be physically transmitted.
Amplitude Modulation and frequency modulation, both are the type of transmission techniques for transmitting information from sender to receiver. But the similarities between the two ends here. Amplitude modulation involves the modulation of the carrier signal according to the amplitude of the baseband signal. The frequency and phase of the carrier signal remain constant.
Amplitude modulation. It is a kind of modulation where the amplitude of the carrier signal is changed in proportion to the message signal while the phase and frequency are kept constant. Phase modulation. This is the modulation where the phase of the carrier signal is altered according to the low frequency of the message signal is called phase modulation. Frequency modulation. In this.

In amplitude modulation, the amplitude of the carrier signal is varied by the modulating signal. There are mainly three basic types of amplitude modulation schemes as described below:1. Double Sideband Full Carrier (DSB- LC)2. Double Sideband- Suppressed Carrier (DSB-SC)3. Single sideband- Suppressed Carrier (SSB-SC)Apart from these three, the other types of amplitude modulations are:4. Single.
The major difference between amplitude modulation and frequency modulation lies in the method of modulating the signal. In amplitude modulation, variation in amplitude of carrier signal according to the message signal is noticed. However, in frequency modulation, the frequency of the carrier signal is changed according to the message signal.
