Question

22. Given the PLL circuit shown below, calculate the minimum Vs frequency that can be captured. (5) 15V R1 5KS2 10 7 FM output 1000 p LMSSSVCO output 1.0 F R R, 4.7nF-Voc 23 Assume the PLL in problem 22 is locked on to the input signal, Vs. What is the minimum frequency Vs can be reduced to and still have the PLL remain locked to it? (6)
