DI Problem 4 (10 points) 2022 Consider a message signal having bandwidth, W = 50 kHz and to be frequency modulated with a frequency deviation constant of kg = 15 kHz/V onto an unmodulated carrier signal having and frequency, fc. tocad max|m(t)= Am V, is such that the average transmitted power to a (a) (2 points) Choose the signal 112 load is Pavg = 32 W. (b) (2 points) Choose the appropriate signal parameter such that the maximum allowable = 75 kHz is achieved. frequency deviation of af 5:43 AM (c) (2 points) Calculate the frequency deviation ratio. Determine the transmission bandwidth which will contain approximately 98\% of the signal power. ess your answer as a (d) (2 points) What is the resulting spectral efficiency? percentage. analm@bypress do equ - spon 20, 2022, 6 (e) (2 points) Using the values calculated above and the Bessel table given below, determine what percentage of the total transmitted power is contained in the carrier only.
