The path length (and therefore, the phase delay) varies, depending on the number of relays that the signal must go through.

依据信号必须通过的继电器数量的不同，路径长度(从而，相位延迟)也发生变化。

If the length of its cyclic prefix is larger than the delay spread of transmission channel, we can get a simple frequency equalizer to demodulate OFDM signal.

对于传统的OFDM系统来说，如果循环前缀的长度大于信道的时延扩散值，则可以通过简单的频域均衡来解调OF DM信号。

For a given conducting medium, the delay is proportional to the length of the signal path.

对于给定的传导介质，延迟与信号通路的长度成正比。

When a conductor makes an announcement about a mysterious, undesired and unscheduled stop, if he or she doesn't know the length of a delay, that's precisely what they will tell you.

The length of the sequester delay remains a problem, reports showed.

Policymakers are still fleshing out the details on the length of the sequester delay, though, and will also have to think of the debt limit, which needs to be raised at some point in the first quarter, according to Nomura.
