message or information signal will be encoded onto the carrier signal. i) Sketch a DSB-SC signal in the time-domain, identifying any key features. Include the message signal in your plot. Describe the key differences between your sketch and that of a DSB- AM signal. ii) Calculate the operating bandwidth of the DSB-SC signal assuming the message signal is audio (40 Hz to 4 kHz). Would this be any different if DSB-AM were used instead? Explain your answer.
