Cheng Xiu-yin · Modern Electronics Technique · 2014
Frequency response of the quiescent point stabilizing circuit was simulated with the software Multisim 10.1. The variation law of the amplitude-frequency characteristics approximate Bode plot of the amplifier circuit was obtained by observation. By the Bode meter,the lower cut-off frequency variation caused by change of the coupling capacity or shunt capacity and the upper cut-off frequency variation caused by change of emitter resistance are analyzed. The conclusion that the simulation result is in accordance with theoretical arithmetic result is achieved. The actual exampleverification shows the reasonable utilization of Multisim 10.1 in the experimental teaching of electronic circuit can make abstract theoretical teaching become more concretely and be propitious to improvement of teaching quality of electronic circuit.
