The audio bandpass filter circuit is an important part of the front-end of audio acquisition in the airborne communication system,and plays an important role in the reliable transmission of voice signals in the communication system.In this paper,the worst-case analysis of the audio bandpass filter circuit is carried out through the Pspice software,the worst-case situation of the performance caused by the combination of component tolerance parameters is considered,the output characteristics of the audio bandpass filter circuit under different component tolerance parameters are analyzed,and the component tolerance parameters that meet the design requirements are found,so as to improve the reliability of the practical application of the audio bandpass filter circuit.
