Signal cable for mining is a signal transmission tool. General signal cable transmission signal is small, in order to avoid the interference signal, signal cable with a layer of shielding layer, outside package of conductor shielding layer, generally for conductive cloth, woven or copper (aluminum), the bronze shield to ground, external interference signal can be the layer into the earth, and avoid interference signals into the inner conductor interference at the same time reduce the wastage of the transmitted signal.
下图五是分立元件组成的反相器振荡电路，这个电路可以通过瞬时极性法进行分析，两个三极管放大电路相耦合，经过倒相两次输入和输出就是同相关系。可以将R4换成扬声器或led，在输出端可以输出振荡信号。这个电路中各元件VTVT2为9013管，RR2=27K-100K，RR4=2K-5.1K，Ec=3v-6v，CC2=0.1-10uF；保证各个三极管工作中放大状态，电路必能起振。图五分立元件反相器组成的振荡电路CD4069振荡电路有两种基本形式，还有一种改进电路；1.振荡电路形式之一，如下图六，该电路的特点是电源的波动将使频率不稳定，适合于小于100kHz的低频振荡情况。

多级阻容耦合放大电路这是一个二级阻容耦合放大电路，前后两级电路形式一致。电路由两级放大电路组成，即以TT2两个三极管为中心的基本放大电路；2.耦合方式为阻容耦合，由电解电容器CCC5作为耦合电容，用来隔断各级的直流偏置并传递信号；根据容抗Xc=1/2πfc，频率、电容越大容抗越小，因此这种电路的高频特性好，当频率低至一定值时，信号几乎通不过；另外为了降低容抗，选用容量较大的电解电容器作为耦合电容。
