- 摘要:
- 本文详细介绍了一种抗干扰性能强的清管跟踪仪接收机的线路组成及性能参数。(1)该接收机采用了有源双T滤波器,大大提高了选择特性(2)该接收机采用的选频放大器比双T型选频放大器滤波性能好,比简单二阶有源滤波放大器稳定性高,具有选频性能好,放大倍数高的优点(3)该接收机采用了三级有源三阶带通滤波器,具有抗干扰性强,工作稳定的性能。
This article deals with circuit components and performance parameters of the pig tracer reciever with good interference resistance system. (1) The selection ability of the reciever in- creases as using the active double T filter (2) The filtering performances of the frequency-se- lected amplifier used in the reciever are better than these of double T, and the stability is higher than the simple 2-step filter amplifer. It has the advantages of good frequaency selected ability and higher amplify multiples (3) As the 3-class and active 3-step band filter are adopted so the reciever has the performances of good interference resistance and working stability.1989,2(2): 38-42 收稿日期：1988-9-27作者简介：作者生于1936年，1963年毕业于北京工业学院电子工程系无线电遥测专业。曾从事导弹信号模拟器、散射通信电台、彩色电视机、清管跟踪仪、管内检测仪等电子仪器的设计与研制工作，也曾从事通信、仪表自动化、节能检测技术工作。现为高级工程师、研究室主任。
