Microwave Communication A reflex klystron is oscillating at the frequency of its resonant cavity. If the reflector voltage is made slightly less negative, the Bunching would occur earlier in time The frequency will decrease Output power would increase Oscillation will cease Bunching would occur earlier in time The frequency will decrease Output power would increase Oscillation will cease ANSWER DOWNLOAD EXAMIANS APP
