The other type of modulation in continuous-wave modulation is the Angle Modulation. Angle Modulation is the process in which the frequency or the phase of the carrier varies according to the message signal. This is further divided into frequency and phase modulation....
Modulation Index fΔ=kfAm. Where kf is the sensitivity of frequency Modulation and Am is the amplitude of baseband signal. 4.1.6 Design of FM modulation and demodulation VCO plays major role in FM signal generation shown in Figure 23. The modulation index determines the volume and sound freque...
Angle Modulation Angle-modulation schemes, which include frequency modulation (FM) and phase modulation (PM), belong to the class of nonlinear modulation schemes. This family of modulation schemes is characterized by high-bandwidth requirements and good performance ...
