1- An FM modulator has a carrier frequency of 200 MHz, is frequency modulated by a sine wave signal at a frequency of (fm= 15 kHz). The resultant FM signal has a frequency deviation of (f= 45 kHz). 4. Sketch, approximately to scale, the magnitude spectrum of the modulator output. Show all frequencies of interest. 5. Calculate the bandwidth occupied by this FM signal?
