The mic also features an extended frequency range response for optimum reproduction and clear sound, while special shock-mounting allows movement of the mic element to greatly reduce handling noise.

麦克风还具有一个最佳的繁殖和清晰的声音频率范围扩展响应，而一些特别的冲击，安装允许麦克风元素运动处理噪音大大降低。

Although this handbook stresses DC measurements, an analysis of noise and instrument response speed requires a brief discussion of time and frequency relationships in electronic circuits.

虽然本书的重点是直流测量，但是要分析噪声和仪器响应速度的问题，就需要简单地讨论一下电子电路中时间和频率的关系。
