When phase noise and phase jitter is doubled, the phase variance increases by
A. Two times
B. Four times
C. 0.5 times
D. 8 times
Answer:A
When phase noise and phase jitter is doubled, the phase variance increases by
A. Two times B. Four times C. 0.5 times D. 8 times
Explanation: In PLL, when the phase jitter and phase noise increases by 2, the phase variance increases by 4 than that of the original signal.
