Degree of modulation-

The modulating wave is given by V_(m)=6sin omegat and the carrier wave is given by V_(c)=12 sin omegat . The percentage of modulation is

Write three important factors which justify the need of modulating a message signal. Show diagrammatically how an amplitude modulated wave is obtained when a modulating signal is superimposed on a carrier wave.

During the process of modulation the RF wave is called

The amplitude of the modulating wave is 2//5 th of the amplitude of the carrier wave. The percentage modulation

The concepts of communication are (a) mode of communication (b) need for modulation (c ) types of modulation (d) detection of modulated wave

An amplitude modulated wave is as given in figure. Calculate the percentage modulation,

In a communication system, what is meant by modulation? State any two types of modulation.

The maximum value of modulation index in case of amplitude modulation system is

The types of modulation which are possible are-

The maximum amplitude of the modulated wave is 16 v and minimum amplitude is 4 V. The percentage modulation is
