(c) directional coupler
(d)
 LCR circuit

ANSWER

EXPLANATION

2. The cavity resonator :

(a) is equivalent to an LC resonant circuit
(b) in a reflect klystron has its output taken from the reflector plate
(c) produces a frequency which is independent of the cavity size
(d) has a low Q factor for narrow operation

ANSWER

EXPLANATION
