9. a) Distinguish between frequency modulated and amplitude modulated radio transmitters. Amplitude Modulation (AM)*: The amplitude of the carrier wave is varied in proportion to the instantaneous amplitude of the modulating signal, while its frequency and phase remain constant. Frequency Modulation (FM)*: The frequency of the carrier wave is varied in proportion to the instantaneous amplitude of the modulating signal, while its amplitude remains constant. 9. b) Figure 4 shows an RLC circuit which may be used to pick up radio signals from a community FM radio. Given values from Figure 4: Resistance, R = 100 \, Inductance, $L = 0.25 \, mH = 0
