| Abstract: | From the basic conception of electric and electronic circuit,proceed from easy to difficult,this paper expounds the method how to analyze the phase. For example,in electronic circuit,such as amplification,oscillation phase shift,feedback and ect.,the question often difficult to cope with except amplitude,is the phase.The paper gives a brief analysis to an example of three 90°phase shiftiong in the principle circuit of PAL decoder. |
