Double Sideband Modulation and Demodulation (DSBSC)
by Emona Tims
LEARNING OBJECTIVES
After completing this lab, students will be able to:
- Generate a real DSBSC signal.
- Examine a real DSBSC signal with scope and compare it to its original message.
- Use multiple message sources in their DSBSC examination.
- Describe the term “depth of modulation.”
- Describe the effects and meaning of over and under modulation of the carrier.
- Compare original and demodulated signals.
- Describe distortion in the recovered signal.
- Identify the effect of phase and frequency errors on the demodulation process.
- Explain the term “product modulation.”
