Consider a FM system that is used to communicate the following message signal: S. m(t) 20 0.05 0.1 015 10 -0.05 with a frequency deviation constant ky 10, and a message bandwidth of W =15 kHz the one-sided noise power-spectral density in the transmission channel is No= 10-8 W/Hz, and an attenuation of 10 is introduced during transmission in the channel as well. a. What is the average-to-peak-power ratio of the message (or, equivalently the power content of the normalized message, Pm=(max(m)? (2.5 points) Pm What is the modulation index (Br)? (2.5 points) b. . What is the channel bandwidth (B.) used for this transmission ?(2.5 points) c. 3
