In other words, the circuit may be physical two - wire (or even physical one - wire) and logical four - wire, performing as a four - wire circuit but employing fewer than four wires.
换句话说,电路可以是物理双线(甚至是物理单线)、逻辑四线,它使用较少的线实现四线电路。
In fact, a four - wire circuit can be established without the use of any wires at all, as in the case with a circuit established over microwave, satellite, or infrared transmission systems.
事实上,可以不使用任何线来建立四线电路,例如通过微波、卫星或红外传输系统。
