The diode detector in an AM radio receiver is usually found _____________?
Correct answer: C. After several stages of amplification
- A. Before the first RF stage
- B. After the first RF stage
- C. After several stages of amplification
- D. None of the above
Explanation
The diode detector is placed after RF and usually IF amplification so that it receives a sufficiently strong modulated signal. It then rectifies and filters the signal to recover the audio envelope.
