Question

Explain the three types of modulation?​

Answer 1

Answer:

There are 3 basic types of modulation: Amplitude modulation, Frequency modulation, and Phase modulation. a type of modulation where the amplitude of the carrier signal is modulated (changed) in proportion to the message signal while the frequency and phase are kept constant.

Answer 2

There are 3 basic types of modulation:

(i)Amplitude modulation,

(ii)Frequency modulation,

and

(iii) Phase modulation

(i)AMPLITUDE  MODUALTION:

Amplitude modulation is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In amplitude modulation, the amplitude of the carrier wave is varied in proportion to that of the message signal being transmitted

(ii)FREQUENCY MODUALTION:

In telecommunications and signal processing, frequency modulation is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave

(iii)PHASE MODUALTION:

Phase modulation 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.
