摘要
本文对一种适用於电话多频系统中作分路滤波器的集成带通(AM 型)电路的性能进行计算机辅助分析,分别计算了由三种小信号集成运放宏模型构成的带通滤波电路的幅频特性、中心频率、增益、3分贝带宽等指标以及各电路元件参数变化对上述指标的影响,即其无源和有源灵敏度。机辅分析计算结果与理论分析完全吻合。计算表明采用简化的宏模型结构可有效地节省计算机时间和内存容量。
This paper introduces the Computer aided analysis of the AM-type band- -pass thick-film circult used for the receiving of multi-frequency coded signals in the Telephone system.Oncluded in the paper is also a caleulation of the Amplitude-Frequency Characteristics,Resonant frequency,gain,Band-wadth of the equivalent circuits consisting of three different types of the macro-models of Integral op-AMP,used in the filter circuit.The effects of changes of the paramaters of presented.element to the specification of the AM-type filter is also. It agrees with the theoretic result and shows that By using the Simplified structur of op-AMP it can greatly shorten the time and memory size of Computer.
