A message signal v(t)=2cos(200m) is applied to a double sideband suppressed carrier (DSB-SC) modulator with carrier signal c(t)=2cos(800000). (i) Derive the frequency domain expression for the DSB-SC modulated signal. [4 marks] (ii) Sketch the magnitude spectrum of the DSB-SC modulated signal. [3 marks] (iii) State one advantage of DSB-SC modulation scheme in comparison to double sidebands large carrier (DSB-LC) modulation scheme.
