It is also referred to as pulse-width modulation. It varies the pulse length or duration around a fixed value. This may be done by shifting either the leading or trailing edge, or both, as a function of the sampled amplitude. Greater channel band width is required tha..

The timing or position of the pulse is varied around a fixed mean value and conforms to the signal amplitude at the time of sampling. A positive signal may set the pulse ahead, a negative signal will set the pulse behind the reference time. In reception, the puls..

Modulation Factor - The ratio of change of amplitude of carrier wave to the amplitude of normal carrier wave is called the modulation factor ..

In this type of modulation, E c , w c are kept constant. The phase angle q of the carrier wave is varied according to the modulating wave. The common name for "phase modulation" and "frequency modulation" is "angle modulation". The digital tra..

(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 noise factor. Frequency modulation..

Let us consider the case of electromagnetic radiation in an ionised medium. Suppose we increase/decrease the amplitude of an electromagnetic wave passing through an ionised gas. These modulations of the electromagnetic wave could contain coded information (Morse code for example). One wo..

A steady current (DC) cannot carry any intelligence. This is because there is no variation in it. However, if it can be changed in some meaningful sequence, then it can be made to carry information (or intelligence). A continuous as wave as such also cannot carry intelligence. This is because it i..
