The linear time-invariant filter can' t improve SNR of single frequency component.

线性时不变滤波不能提高单一频率分量信噪比。

You are less likely to do high frequency component damage with that limiter set to 'on'.

你不太可能与设置'为'的限制器高频部件损坏。

The high frequency component would be absorbed or reflected by the low resistance layer in the crust.

这些电磁波的高频部分将被地壳低电阻层吸收和反射。

Weighing in at less than 9 ounces, it can control a component from as far away as 33 feet, and with an optional radio frequency receiver, it can control components in more than one room from farther away.
