Question 1
What is a key advantage of DSB-SC over standard AM?
- It uses less bandwidth
- It is more power-efficient
- It is easier to demodulate
- It provides higher audio quality
💡 Hint: Think about why suppressing the carrier might help save power.
Question 2
Is the bandwidth for DSB-SC equal to the bandwidth for standard amplitude modulation?
- True
- False
💡 Hint: Recall how bandwidth is determined for each modulation type.

Challenge Problems
Push your limits with challenges.
Question 1
Design a DSB-SC system for an audio signal with a maximum frequency of 3 kHz and a carrier frequency of 100 kHz. Calculate the required bandwidth and explain the implications for the transmitted signal spectrum.
💡 Hint: Think about the implications of the bandwidth calculation and what it means for the frequency range.
Question 2
A DSB-SC signal is generated using a local oscillator that is not perfectly synchronized with the carrier. Discuss the resulting impact on the output and provide at least two specific examples.
💡 Hint: Consider how synchronization affects fidelity in signal transmission.
