Q1. DSB-SC AM Build a Simulink model following Figure 1. D000 00 DSBSC AM Zero-Order Signal Generator DSBSC AM Spectrum Analyzer2 Hold Modulator Passband Scope 1 Scope 2 Spectrum Analyzer1 Figure 1 A DSB-SC AM simulation model in Simulink The DSB-SC AM signal you should generate is x1(t) = cos(2n × 5000t) · cos(4 × 10ªt), where cos(4 x 10*t) is the carrier signal. You should adjust the parameters in the simulation model accordingly and answer the following questions: a. Plot the power spectrum of x1 (t) by hand. b. Verify your power spectrum plot using the result in the spectrum analyzer. You should provide the relevant settings in the Simulink blocks and a screenshot of the spectrum analyzer output to support your verification. c. What should be the simulation time if you want to see 5 cycles of the modulating signal in Scope 1? Show your reasoning and screenshot of the displayed signal in Scope 1 to support your answer.
