How to measure the recording signal current is basically a key problem to the Equivalent Direct current Method.

记录信号电流的计量是磁记录计量另一基本问题，也是等效直流法准确计量的一个关键。

To achieve accurate results, the offset current specification must be smaller than the signal current that is being switched.

为了获得准确的结果，偏移电流技术指标必须小于被切换的信号电流。

This phenomenon alters the distribution of the signal current throughout the wire and changes the effective resistance on the wire .

这一现象改变了通过导线的电流分布、从而改变导线的阻抗，结果是使信号在高频下衰减。

Indeed, recent exchange-rate swings are a signal that current policies are flawed.

ECONOMIST: Dollar danger

Diodes are essential in radios to turn rapidly oscillating radio waves into a smoother direct-current signal that can power a speaker.

ECONOMIST: The middle age of the transistor

The key reason is that by having you come back, the company gets to send a powerful signal to its current employees about how great it is there.
