Teaching Method Research Based on Phase-locked Loop
Wang Yan-fen · Research and Exploration in Laboratory · 2015
With teaching of the curriculum phase-locked loop( PLL) as the starting point,in view of the existing difficulties in PLL application in teaching,we put forward a kind of analogy teaching method,based on traditional PLL about the working principle,combined with the principle of equivalent phase comparison frequency. The method uses the different frequencies phase detection to design the new PLL teaching,and designs appropriate application-oriented experiments. These experiments deepen the students 'understanding and application of PLL. At the same time,the introduction of new theories and new methods stimulate the students 'interest and motivation,and obtain the good teaching effects.
