Question

A carrier of 500 kHz is amplitude-modulated by a 5 kHz audio signal. The upper sideband frequency is:
  1. A
    495 kHz
  2. B
    500 kHz
  3. C
    505 kHz
    Correct
  4. D
    510 kHz

Correct answer

505 kHz

Explanation

USB = fc + fm = 500 + 5 = 505 kHz. LSB = 500 − 5 = 495 kHz. Total BW = 10 kHz.
