摘要

机内通话器模拟输出是输出给电台或记录设备等外部交联设备的模拟信号。为满足机内通话器模拟输出设计功能及指标要求,采用巴特沃斯滤波器系数,使用Sallen-Key结构设计了一个8阶滤波电路,并运用orCAD/Pspice软件对该电路中的元件参数进行优化设计,得到最优带通滤波器的电路参数,并对优化后的电路进行了情况分析,最后通过实验验证了该电路的可行性。
        Airborne communication equipment is an important component of airborne products, implement internal calls on members and external communication.Among them, the analog output part refers to the output to the radio or record sound external crosslinking equipment such as analog signals.Methods to meet the Airborne communication equipment simulation output design, functions and parameters, using butterworth filter coefficient, using Sallen-Key structural design for a 8 order filter circuit, and use orCAD/Pspice element parameter optimization design of the circuit, get the optimal band pass filter circuit parameters, and the optimized circuit is analyzed, finally the feasibility of the circuit is verified by experiment.
