【Abstract】 In view of the design complexity of phase-locked loop in works, the article mainly describes the principle of phase-locked loop and works out the design with SIMULINK simulation toolbox of MATLAB language to construct the model of phase-locked loop and implement the process of simulation. In order to test and verify the effect of the model,with the the help of flexibility and palpability of SIMULINK software,the author analyse several factors associated with following and locking speed of the phase-locked loop, and also revised the parameters of the model to get the optimal program from the simulation result..更多还原
