Which one of the following statements is correct? If a 2-volt instantaneous value of modulating signal amplitude causes a 10-kHz deviation in carrier frequency, what is the deviation sensitivity of the modulator? d) Angle Answer: a Clarification: In linear modulation technique, the amplitude of transmitted signal varies linearly with modulating digital signal. Mar 06,2021 - Pulse Modulation | 10 Questions MCQ Test has questions of Electronics and Communication Engineering (ECE) preparation. Using the Bessel chart of Figure 4.1, what is the bandwidth of an FM signal with a modulation index of 2 being modulated by a 5-kHz signal if we ignore sidebands containing less than 1% of the total power? 5. As the FM modulation index increases, the number of significant sidebands ____________________. The equation for instantaneous frequency fiin FM modulation is fi=fc+kfm(t) Where, fcis the carrier frequency ktis the frequency sensitivity m(t)is the message signal We know the relationship between angular frequency ωi and angle θi(t)as ωi=dθi(t)dt ⇒2πfi=dθi(t)dt ⇒θi(t)=2π∫fidt Substitute, fivalue in the above equation. 6. Modulation has a number of advantages.
