| Abstract: | Aiming at the infl uence of input voltage and static operation point on output waveform distortion of single transistor amplifi er circuit,the parameters corresponding to the static operation point of single transistor common emitter amplifi er circuit are approximately estimated by theoretical analysis,and the phase difference of input and output waveform corresponding to cut-off and saturation distortion is analyzed by drawing method and micro-variation signal equivalent method.The analysis is verifi ed by Multisim software simulation and hardware experiment.Different types of distortion are related to the dynamic voltage confi guration of single tube. |
