Consider the first-order PLL of Example 2.5 in Figure 2.33. Let the amplitude of the sinusoidal input be = 4. Increase the radian frequency of the input starting from ω = 1. At each new value study the tracking performance by plotting the output, the input and the error. Determine ω at which the system loses its ability to track the input. Is there anything that can be done to push this frequency higher? If so, test it by simulation
