Question

The output voltage of phase detector is

• A. Phase voltage
• B. Free running voltage
• C. Error voltage
• D. None of the above

Hint:

The output of the phase detector, which indicates the difference between the input and output phases, is the error voltage.

Answer 1

The Correct Option is C

The output of a phase detector is an error voltage. It is the voltage that indicates the difference in phase between two input signals. This error voltage is then used to adjust the voltage-controlled oscillator (VCO) in phase-locked loops (PLLs).
