Phase Lock Loop Step Response

We analyzed the step response of the phase lock loop using MATLAB and LabVIEW. In the gallery below there is images of a MATLAb Simulation and various LabVIEW oscilloscope measurements of the PLL constructed in the lab. There is general agreement between the MATLAB simulation and the LabVIEW measurements.
