汉语拼音：jiǎn bō

从已调制的电信号中取出原来的调制信号的过程。即调制的反过程，故也说解调。对调幅信号的检波叫振幅检波，对调频信号的检波叫频率检波（即鉴频）。

1. 在无线电接收机中，将高频振荡中的低频用信号分离出来，叫做检波。检波工作可由电子管、晶体管或半导体完成。

• One of the incidental functions of the detector array is the averaging or smoothing of these responses.

  检波器组合的一个附带作用是这些响应的平衡或平稳。

• Earthquakes are recorded with a seismometer, also known as a seismograph.

  地震检波器，也被称为测振仪，可记录地震。

• If we were to try burying our detectors in order to attenuate the surface waves, we would soon grow discouraged.

  如果企图用埋置检波器的方法来衰减面波，很快就会发现这种做法是徒劳的。

• Details are gathered from a worldwide network of seismometers originally set up to monitor nuclear testing, not earthquakes.

  原本用于监视核试验而不是地震的全球地震检波器网络也收集到各种详细资料。

• IF amplifier frequency of the task is to receive the IF signal to be amplified, then sent to detector detector.

  中频放大电路的任务是把变频得到的中频信号加以放大，然后送到检波器检波。

• The optimum design of detector arrays for the attenuation of surface waves and of ambient noise is a complex subject.

  为衰减面波和外界噪声作检波器组合的最佳设计是一件复杂的事情。

• Photo-electronic integrated acceleration seismometer and its digital signal processing system are researched and developed.

  研制出光电集成加速度地震检波器及其数字信号处理系统。

• A device that converts the oscillations of a phonograph needle into electrical impulses for subsequent conversion into sound.

  电唱头，检波器一种把电唱机针的震动变为电子脉冲以使其转变为声音的装置

• The Spirit could also continue to take weather measurements, and its accelerometers could act as seismometers, listening for Mars quakes.

  勇气号还可以继续观测气候。它的加速度计可以用作地震检波器，检测火星的地震情况。
