Phase Locked Loop Quiz

Test your knowledge of PLL block diagrams, lock range, capture range, and standard PLL applications.

Question 1 of 3

Q1.In a first-order PLL, the open-loop DC gain is K = Kd * Kv, where Kd is the phase detector gain (V/rad) and Kv is the VCO gain (rad/s/V). The lock range (hold-in range) of the PLL is:
