(a) The carrier signal with an amplitude of 5 V and carrier frequency of 5 GHz is used I to transmit the message signal m(t) given by m(t) = 0.3 cos(3t). Determine the AM waveform corresponding to the message signal and calculate the percentage of positive modulation (3 marks) If the phase deviation constant is 40 rad/V, then determine the transmitted PM signal (3 marks) (iii) If the frequency deviation constant is 2 x 10 rad/V-s, then determine the transmitted FM signal.
