摘要
本文介绍了小功率医用遥测仪的发射器和接收器的结构,同时基于详细的方块图对接收器各部分的功能、作用和引起接收障碍的机理进行解释,以此证明进行频道转换是必要和有效的。另外在实验数据的基础上对因电波的传输特性不同而引起的接收障碍,也进行了探讨。
Structure of low power medical radio telemetric transmitter and receiver is introduced in this paper. Functions of the receiver and reasons causing reception problem are explained based on detailed block-diagram, which proves the change of channels is necessary and effective. Receiving problems caused by various transmission property of electromagnetic waves are discussed based on experimental data.
