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.
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.
