红外信号收、发系统电路的设计

The Design of Circuits on Infrared Radiation Signal' Recruit and Transmit System

本设计由发射电路及接收电路两大部分组成.在发射电路中采用了三极管发射极的方案,增大了发射机的功率;在接收电路中采用了多级的放大及滤波技术,有效地抑制了噪声,使接收距离长达5米.在功放部分,采用了输入输出滤波电路及电源耦合电路,使带负载能力大为提高,在接上4欧负载时输出波形稳定无失真.

This design is composed of transmit circuits and recruit circuits.Radio triode transmit charge is applied in transmit circuits to increase the power of transmit machines.Various grades are enlarged and wave filtering are applied in recruit circuits to control noises effectively,which makes recruit distance 5 meters long. Input and output wave filtering circuits and power- source coupling circuits are applied in power release,which make capacity abilities more power andoutput waves are steady authentic when connected to 4 - ohm capacity.
