Question: A baseband signal, vm(t) = [a1 x cos(wmt)] + [a4 x cos(4 x wmt)] ++ [a10 x sin(10 x wmt)]. Here wm = [2

radians/s) in the baseband signal. Suppose, this baseband signal amplitude modulates a

A baseband signal, vm(t) = [a1 x cos(wmt)] + [a4 x cos(4 x wmt)] ++ [a10 x sin(10 x wmt)]. Here wm = [2 x (pi =3.1416) (fm in Hz)] %3D denotes the angular frequency (in radians/s) in the baseband signal. Suppose, this baseband signal amplitude modulates a carrier of peak amplitude, 'b' volt and angular frequency (in radians/s), w. = [2 x (pi = 3.1416) x (f. in Hz)] with an effective modulation index, m, leading to a full-AM waveform. Hence, determine the associated entities listed below: (i) Spectral components of the modulated waveform (ii) Percentage efficiency of modulation (iii) Approximate total peak power-levels in the side-bands relative to carrier power-level (iv) Noise power-level across the RF bandwidth in dBm at 300K (v) Effective modulation index, me az volt a4 volt 10 volt b volt fm Hz fc Hz 5 8. 1200 3x106 TK kB J/K 300 1.38064910-23 (i) Spectral Comps (ii) % Power Choices acr x 106 Hz Efficiency w. r.t Carrier dBI Power 2.9988, 2.9952, 2.9880, 1 15.97 0.3800 -1 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 2 15.27 0.3843 -1 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 3 15.38 0.3865 -1 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 15.28 0.3879 -1 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 15.88 0.3888 -1 3.0012, 3.0048, 3.0120 4-
