Subelement E7, PRACTICAL CIRCUITS· Group E7H
Which of the following is a technique for providing highly accurate and stable oscillators needed for microwave transmission and reception?
- A.Use a GPS signal reference
- B.Use a rubidium stabilized reference oscillator
- C.Use a temperature-controlled high Q dielectric resonator
- D.All these choices are correct (correct answer)
WhyA GPS signal reference, a rubidium-stabilized reference oscillator, and a temperature-controlled high-Q dielectric resonator are all techniques for providing highly accurate and stable oscillators for microwave transmission and reception. Highly accurate and stable oscillators for microwave transmission and reception can be built using a GPS signal reference, a rubidium-stabilized reference oscillator, or a temperature-controlled high-Q dielectric resonator, each a legitimate, commonly used technique for reaching the frequency stability microwave work demands, answer D. Since all three are genuinely valid approaches used in practice, no single one alone is the complete answer.
