Types of Analog Modulation
Q. Types of analog modulation are:- Published on 13 Oct 15a. Phase modulation
b. Frequency modulation
c. Amplitude modulation
d. All of the above
ANSWER: All of the above
Modulation is a process by which some characteristics of signal such as amplitude or phase or frequency are varied in accordance with the instantaneous value of the information signal .
The signal whose characteristics are varied is known as carrier signal, as it carries the information. The signal that carries the information is known as modulating signal as according to it, the characteristics of carrier signal are varied.
Methods of analog modulations are
1) Amplitude modulation
2) Frequency modulation
3) Phase modulation
