Why is it desirable to have the modulation index of an AM signal as large as possible without overmodulaion? (iii) For the Amplitude Modulated signal shown in Figure Qu 1, determine: (a) The amplitude of the modulating signal. (b) The frequency of the modulating signal in Hz. (c) The amplitude of the unmodulated carrier. (d) The frequency of the unmodulated carrier in Hz. (e) The amplitude of the upper and lower side band signals. (f) Percent modulation

Step 1
(a) The amplitude of the modulating signal is = -10 + 15 * sin(ωt) = 30 + 10 * sin(ωt) = 40 + 15 * sin(ωt) = 55 + 10 * sin(ωt) = 70 + 15 * sin(ωt) = 95 + 10 * sin(ωt) Show more…
