In Chapter 3 we developed a MATLAB program that can be used to investigate the acquisition performance of a PLL. Using the same baseband model developed in Chapter 3, we now wish to examine acquisition performance in the presence of noise. Assume a perfect second-order PLL. Test the model by observing the number of cycles slipped in the acquisition process due to a step in the input frequency both with and without noise. It is your job to select the noise levels so that the impact of noise is satisfactory demonstrated.
