Explanation: The phase detector compares the input frequency with the feedback frequency and produces output dc voltage called as error voltage. 3. At which state the phase-locked loop tracks any change in input frequency?
A. Free running state
B. Capture state
C. Phase locked state
D. All of the mentioned
Answer:A
Explanation: The phase detector compares the input frequency with the feedback frequency and produces output dc voltage called as error voltage. 3. At which state the phase-locked loop tracks any change in input frequency?
A. Free running state B. Capture state C. Phase locked state D. All of the mentioned
Explanation: In the phase-locked, the output frequency is exactly same as the input signal frequency. So the circuit tracks any change in the input frequency through its repetitive action. 4. Match the list I with list II which represents the three stages of phase locked loop.(PLL)
