(d) FM i. Run the FM function to modulate a cosine message signal with amplitude 2 and frequency

100Hz with cosine carrier signal of amplitude 1 and frequency SDOOHZ. Use the value of

frequency sensitivity constant, kf = 4. What is the bandwidth of the message and carrier

signals? Also answer the following questions: A. What is the frequency deviation Af?

B. What is the value of [3?

C. Is the modulated signal narrowband or wideband? Justify your answer. D. From the plot that you observe, what is the bandwidth of the modulated signal? Compare

it to the theoretical bandwidth of a PM modulated signal. ii. Repeat part(i) with kf = 100 and state your observations.

iii. Repeat part(i) with kf = 200 and state your observations. iv. Which receiver would you use to demodulate the received signal? Justify your answer.
