In a radio receiver, noise is generally developed at _______________?
Correct answer: D. RF stage
- A. IF stage
- B. Receiving antenna
- C. Audio stage
- D. RF stage
Explanation
Receiver noise is generally most significant in the RF and mixer portions at the front end, where weak received signals are first amplified. The RF stage is therefore the intended answer, although external noise can also enter through the receiving antenna.
