What is another term for the mixing of two RF signals?
- A.Heterodyning (correct answer)
- B.Synthesizing
- C.Frequency inversion
- D.Phase inversion
WhyHeterodyning is another term for the mixing of two RF signals. Mixing two RF signals together to produce sum and difference frequencies is classically known as heterodyning, the principle behind every superheterodyne receiver, answer A. Synthesizing, frequency inversion, and phase inversion are different processes that don't describe the basic act of mixing two signals together.
