Question 1.
Figure 4 A basic phase-locked loop
Refer to Figure 4. The block with the ? represents the
• low-pass filter
• VCO
• phase detector
• linear multiplier
Question 2.
When a phase-locked loop is locked, the difference frequency (fi - f0) is• twice the VCO frequency
• equal to the VCO frequency
• zero or very small
• none of the above
