宽频带

That is, the output from the coil is proportional to the time derivative of the current and therefore the obtained result is independent of direct current.

针对直流谐波电流测量幅值小、频带宽的特点及误差要求，分析了传感器及测量电路的灵敏度、误差和频率等性能。

With its broadband characteristic and the ease of manufacturing, transmission line transformers have been widely used in communication.

传输线变压器具有频带宽、易于制作的特点，在通信领域得到了广泛的应用。
