Question: an fm signal has a peak value of 2 volts...

Question details

An FM signal has a peak value of 2 volts, and a carrier frequency of 60 kHz. It is modulated by a message that is a cosine function having a frequency of 20 kHz, and the FM peak frequency deviation is 40 kHz. (a) Sketch the FM signal waveform, vFM(t), over the time interval between t=0 and t=50 microseconds. (b) Sketch the magnitude spectrum of the FM signal, |VFM(f)|.
