A baseband signal, vm(t) = [a1 x cos(wmt)] + [a4 * cos(4 x Wmt)] ++ [a10 * sin(10 x Wmt)]. Here Wm = [2 x
A baseband signal, vm(t) = [a1 x cos(wmt)] + [a4 * cos(4 x Wmt)] ++ [a10 * sin(10 x Wmt)]. Here Wm = [2 x (pi =3.1416) > (fm in Hz)] 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), wc = [2 * (pi = 3.1416) > (fe in Hz)] with an effective modulation index, me 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 3000K (v) Effective modulation index, me a volt a4 volt a 10 volt b volt im Hz fc Hz 5 3 2 8 1200 3x106 TOK kB J/K 300 1.380649x10-23 (i) Spectral Comps Power Choices (ii) % acr x 106 Hz Efficiency w.r.t Carrier Power dB 2.9988, 2.9952, 2.9880, 1 15.97 0.3800 -14 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 2 15.27 0.3843 -14 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 3 15.38 0.3865 -10 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 4 15.28 0.3879 -14 3.0012, 3.0048, 3.0120 2.9988, 2.9952, 2.9880, 5 15.88 0.3888 -10 3.0012, 3.0048, 3.0120 A baseband signal, vm(t) = [a1 x cos(wmt)] + [a4 * cos(4 x Wmt)] ++ [a10 * sin(10 x Wmt)].
