types of modulation

In this type if modulation, w c and q are kept constant. The amplitude E c of the carrier wave is varied in accordance with the modulating wav..

Consider a carrier wave represented by Here e c is instantaneous value, E c is amplitude (maximum value), w c is angular frequency and q is the phase angle of carrier voltage. Corresponding to the three variables E c , w c and q, we can have three different types of modulation..

In this type of modulation, E c and q are kept constant. The frequency w c of the carrier wave is varied in accordance with the modulating wav..

Need for Frequency Modulation - (i) Various electrical machines and noises cause amplitude disturbance in the transmission of amplitude-modulated wave. This makes the reception noisy. So, there is a need for different type of modulation, which can reduce the ..
