9702/41/O/N/15: A carrier wave is frequency modulated. #A2fmP4 #Lv2
(a) Describe what is meant by frequency modulation.
(b) The sinusoidal carrier wave has a frequency of 750 kHz and an amplitude of 5.0 V. The carrier wave is frequency modulated by a sinusoidal signal of frequency 7.5 kHz and amplitude 1.5 V. The frequency deviation of the carrier wave is 20 kHz V–1.

Determine, for the frequency-modulated carrier wave, (i) the amplitude, (ii) the minimum frequency, (iii) the maximum frequency, (iv) the number of times per second that the frequency changes from its minimum value to its maximum value and then back to the minimum value.
