Communication SystemsAM Demodulation

An envelope detector is most directly suitable for demodulating?

  • AProperly modulated conventional AM with carrier
  • BDSB-SC with no carrier under all conditions
  • CSSB-SC without carrier
  • DBPSK only
Report an error
Correct Answer: A. Properly modulated conventional AM with carrier
Explanation: A simple envelope detector can recover the message from conventional AM when a sufficiently strong carrier is present and overmodulation is avoided.
Reference: Standard communication systems: am demodulation
