Which of the following is not a component of basic Phase-Locked Loop (PLL)?

Which of the following is not a component of basic Phase-Locked Loop (PLL)? Correct Answer Schmitt Trigger

Explanation:

  • A phase-locked loop is a control system that generates an output signal whose phase is related to the phase of an input signal.
  • The circuit can track an input frequency or it can generate a frequency that is a multiple of the input frequency.
  • The basic elements of a PLL circuit are a phase comparator/detector, a loop filter, voltage-controlled oscillator (VCO).

The figure shows a schematic of a phase-locked loop:

Hence Schmitt Trigger is not the part of PLL, so option (3) is the correct answer.
