Communication SystemsAmplitude Modulation

A carrier of 1 MHz is amplitude-modulated by a 5 kHz sinusoid. The upper sideband frequency is?

  • A995 kHz
  • B1.000 MHz
  • C1.005 MHz
  • D1.500 MHz
Report an error
Correct Answer: C. 1.005 MHz
Explanation: The upper sideband is fc+fm=1000 kHz+5 kHz=1005 kHz=1.005 MHz.
Reference: Standard communication systems: amplitude modulation
