Question

5. Consider the following message signal: m(t) -2 .3 10 Assume that the carrier frequency is f are kf = 105, kp-25 respectively. 108 Hz, and frequency and phase deviation constants Find the maximum and minimum frequency deviation for FM, and sketch the FM wave for a duration of 103 seconds shown in the above figure (5 points). a. b. Find the maximum and minimum frequency deviation for PM, sketch the PM wave for a duration of 103 seconds shown in the above figure (5 points). c. Assuming the message bandwidth is 15 KHz., estimate the bandwidth of angle modulated signal for FM and PM cases. (5 points). d. Draw the block diagram for the demodulation of angle modulated signal from the theoretical point of view, and show the signals at the output of each block. (5 points). e. Write the MATLAB code for the generation of FM and PM signal, and then for the demodulation of the angle modulated signal. Use a sampling frequency of f,-2 x 108 Hz., and a signal duration of 10 seconds. (5 points). designed to receive frequency band 1 to 30 MHz. With IF 10 MHz, is received at the 10 ar

Answer 1
