application of frequency modulation

In frequency modulation, the frequency of the carrier wave is modified in accordance with the amplitude of the modulating wav..

In frequency modulation, the frequency of the carrier wave is modified in accordance with the amplitude of the modulating wave. The amplitude of the carrier remains unchanged at all times. In other words, the amplitude of the modulated wave remains ..

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 ..

Amplitude Modulation - When the amplitude of high frequency carrier wave is changed in accordance with the intensity of the signal, it is called amplitude modulation. In amplitude modulation, only the amplitude of the carrier wave is changed in accordance wit..

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 d..

Different Types of Modulation - 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..
