Fig. 8 Carrier signal in frequency domain Compare its frequency with the one calculated in time domain. Are they the same? Explain what the following figure is. Fig. 9 AM signal in frequency domain Compare its frequency with the one calculated in time domain. Are they the same? What is the bandwidth of this AM signal? 3. Investigations on the Demodulation of AM Signal Briefly explain the procedures you have carried out. Demonstrate how you have demodulated an AM signal. Explain what the following figure is. Fig. 10 Message signal and the demodulated signal Are the two signals same? Explain. 4. Conclusions Summarize what this report contains. In the last part of this section, explain what you have learnt from this lab experiment.
