The role of circuits in this part is to sense signals sent in vitro through receiving coilcoupling, and then two paths of primary signals are demodulated to be transmitted to a stimulation electrode.
这部分电路的作用是通过接收线圈耦合感应出体外发射来的信号，然后再解调出两路原始信号传输给刺激电极。

The measurement and examination of wave trap coil and coupling filter used for power line carrier communication system are an important part to ensure the electric power system operating normally.
Analysis and operational Suggestions are made on measurement error of moving-coil instrument for thermo -coupling resulted from abnormal operating conditions.
