Superhertodyne principle refers to_________________?
Correct answer: C. Obtaining lower fixed intermediate frequency
- A. Using a large number of amplifier stages
- B. Using a push-pull circuit
- C. Obtaining lower fixed intermediate frequency
- D. None of the above
Explanation
A superheterodyne receiver mixes the incoming signal with a local oscillator to produce a lower, fixed intermediate frequency. Fixed IF stages provide stable gain and selectivity across the tuning range.
