It is easy to demonstrate that amplitude modulation satisfies the superposition principle, whereas angle modulation does not. To be specific, let m1 (t) and m2 (t) represent two message signals and let u1(t) and u2(t) represent the corresponding modulated versions.a) Show that when the combined message signal m1(t) + m2(t) DSB modulates a carrier Ac cos 2πfct, the result is the sum of the two DSB amplitude-modulated signals u1(t) + u2(t). b) Show that if m1(t) + m2(t) frequency modulates a carrier, the modulated signal is not equal to u1(t) + u2(t). A DSB-SC modulated signal is demodulated by applying it to a coherent detector.Evaluate the effect of a frequency error ∆f in the local carrier frequency of the detector, measured with respect to the carrier frequency of the incoming DSB-SC signal.b) For the case of a sinusoidal modulating wave, show that because of this frequency error, the demodulated signal exhibits beats at the error frequency.
