Q. To achieve stable oscillation, Zin + ZL=0 is the only necessary and sufficient condition to be satisfied by the microwave oscillator.
✅ Correct Answer: (B)
false
Explanation: the condition zin + zl=0 is only a necessary condition for stable oscillation and not sufficient. stability requires that any perturbation in current or frequency is damped out, allowing the oscillator to return to its original state.
