The intermediate frequency of an AM superheterodyne receiver is 460kHz and the local oscillator frequency {fLO ) of the mixer is set at the higher of the two possible values, such that fLO > fc always. If the carries frequency {fC of the receiver signal is 700kHz, then the carrier frequency of the corresponding image signal will be kHz
  • a)
    1620 kHz.
  • b)
    1621 kHz.
  • c)
    1622 kHz.
  • d)
    None of these
Correct answer is option 'A'. Can you explain this answer?
Most Upvoted Answer
The intermediate frequency of an AM superheterodyne receiver is 460kH...
Given that fc = 700 kHz
fIF = 460 kHz and fLO > fC
So, the carrier frequency of the corresponding image signal can be given as
fi = fC + 2fIF = 700 + 2(460)
fi = 1620 kHz
